After almost nine years in charge and seven major trophies, Jurgen Klopp is leaving Liverpool.

He has been one of the most transformative managers in the club’s history and in English football’s modern era.

To mark his departure, The Athletic is bringing you the Real Jurgen Klopp, a series of pieces building the definitive portrait of one of football’s most famous figures.

For part five, James Pearce spoke to more than a dozen current and former players, staff members and executives to reveal his managerial secrets.

Read the rest of the series here:

Pep Lijnders takes his time as he ponders how best to sum up the scale of Klopp’s contribution to Liverpool.

What a vantage point he’s had. The Dutchman was there to greet Klopp when he first arrived in 2015 and has been beside him almost every step of the way ever since on his coaching staff.

“In the past 30 to 40 years, not many coaches have changed a club like Jurgen,” Lijnders tells The Athletic. “Louis van Gaal at Ajax, Johan Cruyff at Barca, Pep Guardiola at Barca, Arrigo Sacchi at Milan. Then, for me, Jurgen here.

“Wherever we would have gone in the world, even if we had worn different colours, people would have recognised what they saw and said: ‘Ah, this is Liverpool Football Club’. As a coach, you cannot get a bigger compliment than that.”

Ask the same question about Klopp’s impact at Anfield to Trent Alexander-Arnold and Andy Robertson, the dynamic full-backs who will forever be associated with his reign, and you get a similar answer: this was about far more than trophies.

“Look at the stories that we’ve written, the journeys we’ve all been on,” Alexander-Arnold says. “He’s helped us all develop into what we’ve always dreamed of. He took us to the pinnacle.”

Robertson, nodding in agreement beside him, agrees. “From the moment I walked in through the door, I could sense the belief everyone had in him. It’s been a fun ride. There’s always been excitement. He’s pretty decorated when it comes to silverware, but it’s more a story of how he got a club and fanbase believing again.”

For owners Fenway Sports Group (FSG), there’s also a huge debt of gratitude. “He enthused the club with a competitive spirit that’s really quite unmatched,” says Liverpool chairman Tom Werner. “There’s something in his philosophy of life that bled into the storyline of Liverpool over the past nine years. Here is a man who is not even born in the UK, yet he’s become the Scouser we all love and admire.”

No managerial appointment in Liverpool’s history had created such a sense of fervour.

It was just after 5.30pm on Thursday, October 8, 2015, when Klopp arrived at the city’s Hope Street Hotel. After the Mercedes V-Class he was travelling in had battled past the supporters outside, he headed for The Sixth boardroom to sign a three-year contract alongside Werner, chief executive Ian Ayre and agent Marc Kosicke.

A week earlier, Klopp had flown to New York to meet Liverpool’s owners at the New York offices of law firm Shearman & Sterling after deciding to cut short his sabbatical, five months after leaving Borussia Dortmund.

Werner: “My first impression was that he uses humour in order to make people feel good. Obviously, the position was important to him, but he was also just enjoying a trip to New York City. You could sense his great love of life when we said goodbye.

“After that first meeting, we turned to each other and said: ‘Forget his tactical strategy, he’s absolutely the right person for this club’. We had interviewed other coaches but he was just extraordinarily charismatic. He could be the CEO of any number of big companies outside of football. He has this remarkable ability to motivate people.”

First-team development coach Lijnders, goalkeeping coach John Achterberg and academy director Alex Inglethorpe were among those invited to have dinner with Klopp at Hope Street Hotel after he had signed his contract.

Achterberg: “The conversation just flowed. I felt like I’d known him for 10 years. I thought, ‘Yeah, I’m going to enjoy working for this guy’.”

Inglethorpe: “The day after he came to watch the under-18s play Stoke at the academy. It was clear he had a genuine interest in what we do. An awful lot of managers talk about being committed to the development of young players but only some of them mean it. Jurgen’s commitment never wavered. He made our jobs easier by ensuring that pathway was always clear. I can’t think of another manager who has done it in quite the same way.”

At his Anfield unveiling, Klopp described himself as “the normal one” and urged fans to “change from doubters to believers”.

“If we want, this could be a very special day,” he said. “If you are prepared to work for it, if you are patient enough. If I’m sat here in four years, I think we will have won one title in this time. If not, the next one (job) may be in Switzerland.”

Liverpool were 10th in the Premier League with 12 points from eight matches. They had won just a solitary League Cup since 2006 and had only qualified for the Champions League in one of the previous six seasons as Brendan Rodgers’ reign unravelled following the heartache of missing out on the title in 2013-14.

Klopp waited until the club’s internationals had returned to their Melwood training base before assembling the squad in the media room. Each member of staff on site was asked to pass through and describe their role.

Goalkeeper Simon Mignolet: “They all came through like a train. Jurgen said: ‘Who are all these people?’ Everyone said: ‘They’re the staff.’ He said: ‘No, we’re all one family: the Liverpool family. Everyone has to know everyone’s name. These people are here to help you perform.’ Jurgen’s point was that everyone is a part of the puzzle. That set the tone for everything that came after.”

Melwood gateman Kenny Grimes: “There’s no doubt that the players’ attitude changed towards us. Previously, sometimes they used to drive straight past you but after that (meeting with Klopp), they started to let on a lot more. Everyone just seemed happier, more relaxed. There were never any airs and graces with Jurgen. The culture changed. He made you feel part of Liverpool FC to a much greater extent.”

Klopp, who brought assistants Peter Krawietz and Zeljko Buvac with him, felt that the squad he inherited was talented but weighed down by expectation levels and pressure. He told them: “The only criticism which is really important is mine.”

He brought in new rules about players eating together and reinforced that Melwood was a place of work, not for hangers-on. Time off was reduced as the training schedule became more intensive in order to adapt to his gegenpressing strategy.

As he stood addressing his players, he wrote on the board:

T – TERRIBLE
E – ENTHUSIASTIC
A – AMBITIOUS
M – MENTALLY-STRONG MACHINES

Mignolet: “I remember him saying that ‘terrible’ was how opponents were going to feel after going up against us for 90 minutes. He talked about how we were going to out-work and out-run teams.”

The defining image from his first game in charge — a 0-0 draw at Tottenham — was the sight of a shattered Adam Lallana falling into his arms after being substituted.

Lijnders: “I loved his team talk before that game. He said that Tottenham’s confidence was like a little flower. He stood up and then started stamping his foot down on the floor! That was what he wanted the team to do to the flower! I thought: ‘It’s going to be fun working with this guy’.”

Achterberg: “His force of personality quickly changed the mood around the place. What I liked early on was that Jurgen talked up the standard of the players he inherited. He knew the transfer window was shut and he couldn’t change anything. He immediately got a lot more out of players who had been struggling. He told everyone that everyone would have a fair chance.

“The mantra was: ‘Don’t run forward if you can’t run back’. He said: ‘I’m responsible for the defeats, you boys are responsible for the wins’. He didn’t bulls*** anyone and he was demanding, but working for him was so rewarding. He trusted you to get on with your job and people were prepared to go into battle for him.”

Defender Martin Skrtel: “There was something about the way he talked us as players, the way he motivated us. With Jurgen, he’s real. He’s not playing games. He’s not talking behind your back. That’s why players love him.”

Striker Daniel Sturridge: “It was hearing his voice on the training pitch more than anything. The way he would give his messaging resonated with everyone. It’s hard to get players thinking they’d run through a brick wall for this guy, but he did that.

“With every top manager, it’s teetering on the line of fear and respect. The players need to respect the boss — but the boss needs to command the respect of the players. You have to control the situations at big clubs, and he did that.”

It wasn’t just on the field where Klopp had to alter the mindset. A month into his tenure, he declared he felt “pretty alone” as fans left early when Liverpool trailed Crystal Palace 2-1 at home.

Achterberg: “He felt like the supporters were not fully behind the team. They didn’t really believe. He spoke a lot about that needing to change — how he needed everyone on board.

“Gradually, Anfield became a lot more positive. Critics said Jurgen was celebrating a point when he got the players to hold hands in front of the Kop after Divock Origi got a late equaliser against West Brom, but they missed the point. That was his way of saying: ‘Thank you, this is what’s possible if we all stick together’. The first big example of that was the fightback against Dortmund (in the Europa League). That underlined how he had tapped into the power of Anfield.”

Liverpool trailed 4-2 on aggregate in the second leg of the Europa League quarter-final with just 25 minutes to go but goals from Philippe Coutinho, Mamadou Sakho and Dejan Lovren stunned Klopp’s former club.

Lijnders: “I believe that the character of the leader becomes the character of the team. You get a passionate guy coming in who really knows what he’s doing and why he’s doing it. He had the experience of knowing what works and came with new football ideas. People started seeing development and the people around him were able to express themselves freely.”

In December 2015, the players had expected their Christmas party to be cancelled after a 3-0 defeat to Watford. Instead, they received a message from the manager that read: “Whatever we do together, we do as well as we can and tonight that means we party.” Nobody was allowed to leave Formby Hall, a golf resort and spa complex near Liverpool, until 1am.

By the end of the season, Liverpool had competed in but lost two major finals: the League Cup to Manchester City (on penalties) and the Europa League to Unai Emery’s Sevilla.

Determined to lift spirits at the post-match party in Basel’s Novotel, Klopp grabbed the microphone and said: “Two hours ago you all felt s***. But now, hopefully, you all feel better. This is just the start for us. We will play in many more finals.” He then launched into a defiant rendition of “We Are Liverpool”.

Achterberg: “Jurgen was adamant that the party should go ahead. He said sometimes you have to lose in order to learn how to win.”

Alexander-Arnold: “Especially early on, as a young player coming through at such a big club, you go through a lot: the demands, the pressure, the expectation. Jurgen helped me so much. He put an arm around me and took the pressure off. He talked to me about managing my emotions. He knew when a bollocking was needed, or a little bit of love. He helped me go from being a young player breaking through to being a leader of this team. I owe him so much.”

Signing players with a point to prove appealed to Klopp. Robertson arrived in the same window for £10million after being relegated with Hull City. Wijnaldum had suffered the same fate with Newcastle United.

Robertson: “It’s pretty rare that a big club signs you off the back of something like that. The first time I met Jurgen, it was at Melwood; he had just flown back with the squad from Asia. He walked over, gave me a big hug and welcomed me to the club. He explained what he thought about me as a player, where he thought I could improve, how he wanted me to play. I believed in every word he said.

“The club had just got back into the Champions League and it felt like the first steps of the journey. You could see how much belief everyone had in him. The whole club was connected. Before, from the outside looking in, it didn’t look that way. Part of that was signing good characters: people who could carry his messages within the changing room as his eyes can’t be everywhere.”

Salah, Mane and Firmino netted 91 goals between them in 2017-18. Salah, who was crowned PFA Player of the Year and FWA Footballer of the Year, set a new best of 32 league goals over a 38-game season as he scored 44 times in all competitions.

When Coutinho belatedly got his wish and was sold to Barcelona for £142million in January 2018, there were concerns that Liverpool’s charge would be derailed but Klopp didn’t share them. He felt that too often team-mates looked to the Brazilian to provide the creative spark and that without him they would become more unpredictable.

He was proved right. It helped that £75million of the fee was spent on the transformative signing of Virgil van Dijk from Southampton.

Lijnders: “We could play a higher line with Virgil — more aggressive because of how he deals with space and longer balls.”

With Van Dijk, Liverpool surpassed all expectations in reaching the Champions League final in Kyiv. Ahead of the game with Real Madrid, Klopp sought to relieve the tension in a team meeting by lifting up his top to reveal he was wearing Cristiano Ronaldo-branded boxer shorts.

Wijnaldum: “Everyone was laughing their heads off. That really broke the ice. Usually in those situations, everyone is serious and concentrated. But he was relaxed. He is a father figure for players and a really special man for me. He really cares about the welfare of a player and wants to know you away from football.”

The tears flowed in the Liverpool dressing room after the 3-1 defeat to Zinedine Zidane’s side. Karius sat with his head in his hands after gifting Madrid two goals with glaring errors. Salah was crestfallen after being forced off with a shoulder injury.

Alexander-Arnold: “In terms of team talks, the biggest one for me was the messaging Jurgen gave us after Kyiv. He said: ‘This defeat is not going to define us. As a group, we are going to get back here. This is where we’re destined to be.’”

When Klopp finally made it back to his house in Formby just after 6am, the beer flowed and he led a sing-song with old friends including Krawietz, Campino, the lead singer of German punk rock band Die Toten Hosen, and Johannes B Kerner, a well-known German TV personality.

The big dilemma for the manager was the goalkeeper situation and how to handle a distraught Karius. His compassionate instinct was to wrap an arm around him and rehabilitate his Liverpool career rather than show him the door.

Four days after the final, Klopp received a call from Germany legend Franz Beckenbauer, who alerted him to the possibility that Karius may have been concussed by a blow to the head from Madrid’s Sergio Ramos shortly before his first costly blunder of the final.

Karius, who was on holiday in the U.S, was sent to see a specialist in Boston. Brain scans showed Karius had ‘visual-spatial dysfunction’, which can result in an inability to judge where objects are. “What the rest of the world is making of it, I don’t care. We don’t use it as an excuse: we use it as an explanation,” insisted Klopp, who branded Ramos “a brutal wrestler”.

Publicly, Klopp talked about a fresh start for Karius but the ‘keeper was a bag of nerves the following pre-season. His confidence was shot to bits.

Behind the scenes, Liverpool had been working on a replacement long before the Champions League final. Klopp didn’t have complete faith in either Mignolet or Karius, which created uncertainty and a degree of resentment between the two ’keepers.

Achterberg: “It was a really hard situation for Jurgen and all of us to deal with. We played Chester away in the first friendly after Kyiv. I kicked the ball towards Loris during the warm-up and it went straight through his hands and legs and into the net. Someone filmed it and it went viral on social media. Then we played Tranmere and he dropped the ball and they scored.

“I’d been watching Alisson’s development closely since (ex-Roma and Liverpool goalkeeper) Alexander Doni told me about this guy coming through at Internacional in Brazil. The problem was he didn’t have an EU passport, which meant we couldn’t have signed him when he went to Roma in 2016.

“When we played against Ali in a pre-season friendly in the States (in August 2016), I told Jurgen: ‘This is the one I was telling you about’. I kept watching and writing reports on every game he played. I spoke to all the recruitment guys about him.

“There was a meeting in January 2018 with Ali’s agent when we said how highly we rated him. That summer, the club were going to sign midfielder Nabil Fekir from Lyon but they backed out because he had a bad knee (a fee of £62million had been agreed).

“If the Fekir deal had gone through, would we have had the money to sign Alisson? Things certainly turned out for the best. I told the boss that Ali was the one. We needed to move quick in mid-July because we knew Thibaut Courtois was leaving Chelsea (to join Madrid) and they needed a replacement.”

Initially quoted £90million by Roma, Edwards negotiated a £65m deal for Alisson. It was the final piece in the jigsaw.

In his first season at Anfield, he won the Premier League Golden Glove for most clean sheets (21) and was crowned goalkeeper of the year by both UEFA and FIFA. Klopp would walk around Melwood singing “All you need is Al-i-sson Beck-er” to the tune of Queen’s Radio Ga Ga.

There was also a significant change among the backroom staff. Lijnders had left Liverpool in January 2018 to manage Dutch outfit NEC Nijmegen but he returned just four months later after Klopp offered him the assistant manager’s job. The vacancy had arisen following the exit of Buvac, who had become increasingly distant as relations strained with other staff members.

Lijnders: “Jurgen gave me responsibility for the entire training process and that was very important to me. I wouldn’t have come back just for my old job. It meant I could continue with the things that I loved: planning training, delivering training, finding tactical and strategical plans. We challenged each other.

“I’ve known him for nine years and he still surprises me every day. I always loved the meetings in Jurgen’s office the day before each game. That’s where you decide who starts, how we’re going to build the game, how we’re going to press them, what the messages to the players will be. Things become clear in our heads before we speak with the team.”

Klopp then made some subtle changes to Liverpool’s blueprint. “We need more game management and control,” he explained. “Everyone talks about our intensity but sometimes when we run like devils, I have to say, ‘Come on, please cool down’.”

Prior to 2018-19, he prioritised improving Liverpool’s output from set pieces. Lijnders and Krawietz were tasked with coming up with the routines to make them count. By the end of the season, Liverpool were top of the Premier League set-piece goals table with 29.

Klopp the innovator was always seeking marginal gains. That summer, he recruited specialist throw-in coach Thomas Gronnemark after reading about his work in a German newspaper.

Gronnemark: “Before I met Jurgen, it was frustrating. I had all this knowledge about how to keep possession from throw-ins and create chances, but people didn’t want to listen. They only wanted long throw-ins. The first club that took it all on board was Liverpool. That says a lot about the mentality and the culture Jurgen created at Liverpool.”

Fast forward to May 7, 2019, and Liverpool went into the second leg of their Champions League semi-final with Barcelona at Anfield 3-0 down and needing a miracle to avoid finishing the season empty-handed.

The previous night, title rivals Manchester City had beaten Leicester City courtesy of Vincent Kompany’s piledriver to remain masters of their own destiny. For the Barca game, Salah was sidelined by concussion and Firmino was injured.

Robertson: “The morning of the Barcelona game really stands out for me. The way he spoke and addressed Kompany’s goal, which pretty much finished the title race. It was like: ‘Right, does anyone want to say anything about what happened last night? No, right, here we go’.

“Then in the team meeting at the hotel, he said: ‘For anyone else, this is impossible, but because it’s you lot, there’s a chance.’ Belief built by the hour. You could sense it. You just couldn’t wait to get to Anfield. The changing room before the game was the loudest one I’ve ever been in.”

Achterberg: “He said to the boys, ‘Close your eyes and imagine the best game you have ever played. Go out there and write a story to tell your grandkids one day’. The words were perfect. It was the greatest night ever at Anfield.”

The 3-0 deficit had already been wiped out when Alexander-Arnold’s quickly taken corner caught Barcelona napping and Origi swept home Liverpool’s fourth goal.

Alexander-Arnold: “That night epitomised what Jurgen had created. The mentality he had instilled in us that no matter what position we’re in, whoever we’re up against, we just believe that anything is possible. It’s happened so many times. All those fightbacks, all the late winners.”

Werner: “I was watching the game with John Henry in Boston. It will be etched in our memories forever. The fourth goal was just crazy.

“The sense of unity Jurgen had created was clear. I had the privilege of watching training one day and Jurgen got everyone in a circle to tell them it was Sadio Mane’s birthday. He got Sadio to sing ‘Happy Birthday’ in his native language and then turned to Virgil and said, ‘Why don’t you sing it in Dutch?’ Then he turned to Mo Salah and said ‘Why don’t you sing to Sadio in Arabic?’ On it went with everyone laughing. I just thought, ‘What a wonderful way to start the day.’”

Despite achieving a club-record haul of 97 points and losing just one league match all season, the Premier League title eluded Liverpool on the final day as City finished one point clear. “That was our first chance to win it — not our last,” Klopp reassured his players.

The three-week gap to the Champions League final in Madrid wasn’t ideal but a friendly was arranged with Benfica’s B team at Liverpool’s training camp in Marbella as their style and formation was deemed similar to opponents Tottenham.

Klopp, who was bidding to end a run of six successive final defeats as a manager, was so relaxed he had a two-hour sleep in his hotel room on the afternoon of the final.

Robertson: “The night before in the stadium, he got us all in a circle. He said: ‘This is where we become Champions League winners tomorrow night’. It made the hairs on the back of your neck stand up. You just thought, ‘Yeah, this is it’. From the heartbreak of the year before in Kyiv, the feeling was: ‘Get us to that game, let’s do our job and get our hands on that trophy.’”

“Let’s talk about six, baby,” beamed Klopp after Salah’s early penalty and Origi’s drilled finish late on sealed the club’s sixth European Cup. “Did you ever see a team like this, fighting, with no fuel in the tank? They suffer for me. They deserve it more than anybody.”

The celebrations inside the club’s private party in Madrid’s Eurostars Hotel went on until dawn. There was a symbolic moment when Klopp and friends, including Campino, headed to a side room to record an impromptu follow-up to their song from a year earlier:

We’re sending greetings from Madrid,
Tonight we made it number six,
We brought it back to Liverpool,
Because we promised we would do.

Around 750,000 people turned out in Liverpool for the homecoming parade. “If you could’ve put all the emotions, all the excitement, all the love in the air that day and bottled it up, the world would be a better place,” Klopp said.

With captain Jordan Henderson and vice-captain James Milner around, there was never any danger of standards slipping.  The 2019-20 season was one of ruthless and relentless consistency. There was no title race, just a procession. Klopp’s men took 79 points out of the first 81 on offer and lifted the European Super Cup and Club World Cup along the way. Everyone played their part, but the full-backs were so influential with the quality they provided from wide areas.

Robertson: “It was intense but the way the manager wanted us to play suited Trent and I in terms of trying to create. It was a massive part of our success, overloading the wide areas, having the three of us — myself, Gini and Sadio — more often on the left, and then Trent, Hendo and Mo on the right, trying to create overloads.

“But we also had to be part of a strong defence. When Jurgen first came in, they were winning games 5-4 like the one at Norwich. That more often than not doesn’t win you titles. You have to be able to keep clean sheets.

“There are lots of elements to his philosophy — like when we lose the ball, reacting quickly to win it back. That’s especially important against deeper-lying, low-block teams. That’s when spaces open up because maybe one of them is out of position. It was full throttle. You knew you needed to be at 100 per cent every game. It wasn’t as controlled as some other teams but you knew when you played against us, you had to outrun us and want it more than us to have a chance.”

Lijnders: “If players feel inspired, if they feel like they’re improving, there’s nothing better. If you work for a long time with the same group, you need to dress up well. It’s the same if you’re in a marriage! You always need to find new ways to inspire. The reason why we were successful is our players had unbelievable character, potential and attitude. We created stability by keeping Jurgen, staff and players together, always doing the same type of work on the training pitch.

“In the best games, it was our counter-pressing that made the big difference; not waiting for things to happen. When emotions become high, players forget the tactical plan. It’s the training and the repetition that makes the difference.”

In the summer of 2019, Klopp recruited performance psychologist Lee Richardson. He also invited German big-wave surfer Sebastian Steudtner to speak to the players about managing stress and teaching them breathing techniques.

Richardson: “Jurgen is the best communicator I’ve ever seen. The head psychologist at Liverpool is Jurgen in many ways. He’s the one who affects most people with everything he does — with every team talk he gives, every decision he makes. The role of the actual psychologist is about being a support for different things that the manager can’t always be dealing with.”

With Liverpool on the cusp of ending their 30-year title drought in March 2020, the season was suspended due to the Covid-19 pandemic. The players assembled in the canteen at Melwood when Klopp told them: “Don’t worry about football for now. You are the best team in England and the most worthy champions there has ever been.”

The triumph was belatedly confirmed on June 25, 2020 after Manchester City lost to Chelsea. Liverpool were an unassailable 23 points clear of City with seven games remaining.

Alexander-Arnold: “We knew there was a chance it could happen, so Jurgen got everyone together for a barbecue. You never grow up dreaming of becoming a Premier League champion sitting at Formby Hall in the middle of a global pandemic! You think about a last-minute winner that snatches it, a full house at Anfield, celebrating with the fans.

“But it was still a special one for us. It was such a dominant season. We blew every team away. Looking back on that season, I don’t see how any team could have beaten us with the mentality that we had. We won games in so many different ways.”

Klopp was reduced to tears as he went around hugging his players. His knack of making even those on the fringes of the squad feel important was underlined on the night Liverpool lifted the Premier League trophy after beating Chelsea at Anfield. Turning to his fourth-choice goalkeeper, he said: “Andy Lonergan, champion of England, champion of Europe, champion of the world. What a guy!”

The players responded by chanting the name of someone who had not made a single appearance for the club.

GO DEEPER

Liverpool’s 30 years of hurt

Having scaled such heights, Liverpool fell quickly – despite the arrivals of Diogo Jota from Wolves and Thiago from Bayern Munich. For a team that fed off the emotional energy in the stands, playing behind closed doors during the pandemic was a hard, soulless slog.

Klopp also had to deal with the personal anguish of losing his mother Elizabeth and not being able to travel home to Germany for the funeral due to travel restrictions. On the field, Liverpool had a centre-back crisis after Van Dijk, Joe Gomez and Matip all suffered season-ending injuries. Playing Henderson and Fabinho in the back line didn’t work as it weakened the midfield. Klopp turned to rookies Nat Phillips and Rhys Williams to help salvage their top-four hopes.

Phillips: “I look back on that period with a lot of pride — it brings a smile to my face. I’d only played once for Liverpool before that season: the FA Cup tie against Everton the year before when Curtis Jones scored a brilliant winner. Jurgen placing his faith and trust in me was a huge boost. He was always providing reassurance. He was very complimentary about me in the press. He made me feel that I deserved to be there.

“Before I was exposed to first-team football, I always had the impression there would be big personalities and big egos in there. But what struck me was that no one in that dressing room thought they were better than anyone else.”

Lijnders: “We had to keep each other positive. The moment I became negative, Jurgen became positive. When he was negative, I stayed positive – that’s the best way to describe it. The mindset was always, ‘What do we have?’ Not, ‘What don’t we have?’”

Robertson: “Even during the tough times, I don’t think anyone ever doubted the manager – you always felt he would find a way out of it. Of course, there were days when his energy wasn’t as high, results weren’t great, and times when we had to lift him.

“At the start of that season, if you had said we would be relying on Nat and Rhys to get us into the Champions League I don’t think many would have believed you. But Jurgen found a way. After all the problems we faced, it felt like a massive achievement.”

Liverpool took 26 points out of the last 30 on offer to finish third in 2020-21. The highlight of the run-in was Alisson’s headed winner at West Bromwich Albion in the last minute of stoppage time. He became the first goalkeeper to score a competitive goal in the club’s 129-year history.

Achterberg: “I thought maybe Ali could be a nuisance in their box — but I wasn’t expecting that! There was a lot of passion on the bench because we were so desperate for that win. Ali’s part in the story is so big. Without the save he made late on against Napoli (to deny Arkadiusz Milik in the Champions League group stage in December 2018), there would have been no run to Madrid, no European Cup, no Super Cup or Club World Cup.

“Jurgen joked that if he had known Ali was this good he would have paid double. With Caoimhin Kelleher, we created the best goalkeeper department the club has ever had.”

Liverpool are set to appoint Arne Slot as their new head coach — and The Athletic has every angle covered.

Klopp’s “mentality monsters” kicked on during a breathless 2021-22. Both domestic cups were won on penalties against Chelsea at Wembley with the manager saluting the “incredible impact” of Neuro11, the German neuroscientists that had been recruited to work with the players on dead-ball situations. Liverpool scored 17 of their 18 spot-kicks across the two shootouts.

Quadruple talk gathered pace but Liverpool missed out on the two biggest prizes by the finest of margins. Once again the title race went down to the final day. City’s late fightback from 2-0 down to beat Aston Villa 3-2 ensured they finished a point clear.

Achterberg: “Jurgen never talked about City. His attitude was: ‘We only play them twice a season, so why worry?’ You can’t influence what they do. We knew that City had much greater resources but we were so close to winning the lot that year.”

On the same night that Liverpool beat Villarreal to reach a third Champions League final under Klopp, on-loan Phillips was celebrating helping Bournemouth win promotion back to the top flight.

Phillips: “My phone buzzed with a message from Jurgen. He thanked me and Rhys for the part we had played in getting them into the Champions League the season before. The fact he had us in his mind at that time says a lot about him.”

The chaos outside Stade de France blighted the showpiece occasion in Paris. On the field, Liverpool were thwarted by the heroics of Real Madrid goalkeeper Courtois and Vinicius Junior’s goal.

Werner: “We spent a lot of time with Jurgen in Paris after that defeat. It was so discouraging because we all felt we were the better team on the night. If we replayed that match 10 times, we probably win eight. But Jurgen was so optimistic about the future. He was far more cheerful than any of us.

“He has such a unique perspective. There’s that famous quote that ‘football is the most important of the least important things in life’. Jurgen knows that football at its best is a real tonic for people. He appreciates the wins but keeps the losses in perspective. He articulates himself after a defeat in such a way that it soothes your pain. He carries that balance. It’s demonstrated in his relationship with the team, his staff, the supporters and the city. He always has a grasp of the bigger part.”

Having built one great team, Klopp set about assembling another. The frontline evolved with the signings of Luis Diaz, Darwin Nunez and Cody Gakpo. But he over-estimated what some loyal servants had left in their legs after an energy-sapping 63-game campaign.

The 2022-23 season was bleak as an ageing midfield was repeatedly over-run and injuries cut deep. The tactical tweak of moving Alexander-Arnold into the centre when Liverpool were in possession sparked a late revival but it was in vain as they missed out on a top-four finish.

Henderson and Fabinho were lured away by Saudi Arabia’s riches, following the departures of Milner, Keita, Firmino and Alex Oxlade-Chamberlain as free agents. The midfield overhaul saw Alexis Mac Allister, Dominik Szoboszlai, Wataru Endo and Ryan Gravenberch recruited.

Lijnders: “Jurgen and I had good talks last summer about the future. We said, ‘OK, let’s do one more year, see how it goes’. I said to all the guys at the start of pre-season: ‘The first one who is negative, I’ll punch in the face!’ We needed a reset with new players and that worked out well. It must have been late October or November that Jurgen and I had some good talks.

“We both came to the conclusion that the right thing to do was to go at the end of the season. Jurgen had made his mind up and I was quite clear that it was the right time to make my own way. We wanted to leave the club with Champions League football and a team the next manager can really take care of. I think we did the right thing.”

When Van Dijk’s extra-time header secured Carabao Cup glory against Chelsea at Wembley in February, Klopp described it as “easily the most special trophy I’ve ever won”. At the time, he was wrestling with an injury crisis and turned to youth. Harvey Elliott, Conor Bradley, Jarell Quansah, Bobby Clark, James McConnell and Jayden Danns all played their part.

Who’s who on Team Klopp

Inglethorpe: “Jurgen believes that anything is possible, and puts young players at ease. I would have wanted to play for him. Whatever talent you have, he would get the best out of you; that’s a magical quality. He’s consistently given young players a stage to play on and when it’s been best for their career to move on, he’s done it with care and thought. He will have a seat at the top table when people talk about the all-time greats who have managed this club.”

After Klopp publicly announced in late January his decision to stand down and take a break from football, there was a period when it looked like he would get the perfect farewell as Liverpool rode a wave of emotion. However, they couldn’t sustain it and their challenge for further honours wilted.

But his status remains undimmed. What a ride it’s been, and what a legacy he’s leaving behind, one that will be celebrated at Anfield on Sunday by many of the people who shared in the journey.

Alexander-Arnold: “It’s going to be a hard transition for us as players. It’s an emotional one. It’s going to be very difficult to say goodbye. It’s one that I’ll never be ready to do, to be honest. The only thing I can really say to him is ‘thank you’. Everything I’ve achieved is down to him and the opportunities he gave me. When I’m done with football, I’ll look back and think of the years we spent together as the most fun, the best and the most important.”

Achterberg: “Look where Liverpool were when Jurgen arrived and where they are now. As well as the trophies, look at the new training ground and the redevelopment of Anfield. He won everything and fulfilled all our dreams. He created one of the best teams European football has ever seen and brought joy to so many people.”

Werner: “It’s about far more than the trophies. Look at the number of young players from the academy who surpassed expectations. Jurgen is a very selfless man. Part of the love people have for him is that he really understands the club and the relationship the club has with the supporters. The idea of him ever coaching another Premier League team is absurd. It just wouldn’t happen. He’s got LFC tattooed on his heart.”

Robertson: “Without him, what I’ve achieved in football wouldn’t have been possible. He gave us the best time of our lives. When my kids were born, he was one of the first to congratulate me and make sure my wife was OK. Those are the kinds of things you don’t forget. In the seven years I’ve been here, a lot has happened in my life and he’s been a key support throughout on and off the pitch. I will look back on it when I’m old and grey and think, ‘Without him, it wouldn’t have been possible’.”

Lijnders: “‘Unforgettable’ is the word I would use. I feel really blessed that we could stay so long at a club and conquer so many major trophies. What an honour it’s been — to work with Jurgen Klopp, to be part of something so beautiful.”
