Few players are driven to club soccer practice by a national team player. But then few players have two sisters who play for the U.S. women’s team.

Also Zoe Thompson is just 14, so you can’t expect her to drive herself.

But here’s the thing that truly sets Zoe Thompson apart. Although eldest sister Alyssa, 21, has already played in a World Cup and middle sister Gisele made 38 NWSL appearances and played four times for the national team before her 20th birthday, Zoe may actually be the best of the three.

“She’s better technically,” said her father Mario Thompson, who coached all three.

“I think she’s the combination between Alyssa and Gisele,” said Carlos Marroquin, owner of the pre-professional women’s team that gave Alyssa and Gisele their start.

So maybe there should be a line of coaches, teammates and family members waiting to drive her to practice or to her debut with Marroquin’s team, the Santa Clarita Blue Heat, on Saturday evening at The Master’s University.

The team, which competes in USL W league, has long been a summer proving ground for elite college players and aspiring pros with alumni that includes Venezuela’s Deyna Castellanos, once a finalist for FIFA’s world player of the year award; World Cup veterans Savannah DeMelo and Ashley Sanchez; former Chelsea and Atlético Madrid star Ana Borges of Portugal; and Natalia Kuikka, a five-time Finnish player of the year.

This year’s roster includes more than two dozen Division I college players, meaning Zoe Thompson will be playing with and against women much older than her.

Did we mention she’s still in middle school?

“She’s always having to get out of her comfort zone, no matter what,” said Mario Thompson, whose job as Zoe’s father is to both nurture and protect his daughter’s talent.

Zoe has followed a different path than her sisters. Alyssa and Gisele were born less than 13 months apart and grew up playing together, practicing together and pushing each other. Zoe, born seven years later, grew up watching them, imitating them and wanting to be them.

But she had to do the work alone.

“It’s a unique dynamic where Alyssa and Gisele had each other,” their father said. “It wasn’t just Alyssa by herself. She always had a partner.”

Zoe, however, observed a lot by watching.

“I feel like their mistakes helped me,” she said. “But at the same time, there are some mistakes that I’ve made that they haven’t. I’m learning differently, but I’m more learning from them.”

Still, this is uncharted territory. No family has ever had a trio of siblings play for the women’s national team, and the pressure of having to match the success her sisters have had will be inescapable, if unfair, for Zoe.

It’s a level of pressure that has the potential to be crushing.

“She kind of has this expectation that’s put upon her already that ‘oh, she’s going to be like her sister,’” Gisele said. “But it’s her own life.”

And Mario Thompson, an elementary school principal who has been intimately involved in all his daughters’ careers, is having to negotiate all this on the fly.

“Everyone sees the glam and the glitz of Alyssa and Giselle, but people don’t really understand it’s a lot of pressure,” he said of the sisters, who will both be heading to Brazil with the national team next week. “They see all the great stuff, but it’s also their job.”

Mario Thompson faced some of the same issues with Alyssa, the second-youngest U.S. woman to play in a World Cup, so he limited her media interviews and tried to let her be a teenager — albeit it an exceptionally talented one. Zoe faces the additional burden of having do all that while following in her sisters’ footsteps.

“I’m very mindful and aware of that,” he said. “She’s already in the spotlight without having to be in the spotlight. It’s that pressure. I want her to love the sport, love this journey. That’s kind of how I raised all three of them.”

For her part Zoe, mature well beyond her tender age, dismisses the hype with a shrug.

“There are going to be comparisons,” she said. “But we’re such different people that I think it’s unfair. At the same time, they can have those comparisons, they can have those opinions, but I’m not them. So it’s not going to be any different, how I play.”

Plus, having two accomplished sisters has its advantages. In the spring Zoe trained with the youth teams at Chelsea, where Alyssa now plays, and this summer she says she’ll train with Angel City, Gisele’s team. But the drawback of being a (much) younger sister is Alyssa and Gisele had each other to lean on growing up. Zoe has had to go it alone and that, she said, has made her stronger.

“Mentally, it is harder. But seeing my sisters and where they are, it’s kind of a motivation for me,” said Zoe, who has already been called in three times by the U-14 national team. “They were kind of at the same place I am. And it’s just very motivating to see them where they are. That’s just kind of where I want to be.”

If there’s been one constant in the girls’ soccer careers it’s been their dad, who has been intimately involved in with all three, drilling them in the backyard of their Studio City home or walking them down the street to a park, where they shared the lumpy grass with softball players and unleashed dogs.

They were often, but not always, willing participants since the family didn’t have a TV when the girls were growing up.

And while the hours and hours of practice certainly honed the sisters’ skills, their parents can’t explain where the girls got their immense physical gifts. Mario played football and basketball and ran track at Occidental College with modest success while his wife, Karen, an occupational therapist, played basketball and ran cross-country in high school, hardly the pedigree that could be expected to produce three world-class soccer players.

Perhaps part of the answer lies in their unique DNA, a mix of Mario’s Black and Filipino background and Karen’s Italian and Peruvian roots.

“It was never the plan, ‘Hey, let’s have some soccer players’,” Mario said.

But once the sisters decided that was their plan, the parents had to adjust. The girls had rare talent, Mario Thompson quickly realized, and it had to be developed. So Alyssa and Gisele began playing with an elite boys’ team while they were still in high school and passed up scholarships to Stanford to sign lucrative contracts with Angel City while their were teenagers.

Zoe has chosen another way, playing with Tudela FC, an all-girls team that practices near her home, and with the Blue Heat, where she’ll be facing stronger, more mature players for the first time. Mario Thompson hopes those aren’t the only differences, although he said the road his youngest daughter takes will ultimately be up to her.

“My hope is she goes through college and just goes a different pathway, different journey,” Mario Thompson said. “It’s a roller-coaster ride and so for [Zoe], I think she sees that roller-coaster ride and I don’t know if it’s a rush to let me get to that. She wants to eventually be a pro, but I don’t think it’s ‘I need to get there as soon as possible.’”

“It’s Zoe, what do you want?” he added. “It’s not like you have to be here, you have to do this. It’s none of that. It’s about, ‘Hey, Zoe, this is your journey.’ We want you to enjoy it, have fun with it, be happy with it.”

She appears to be accomplishing all three of those goals. She’s also both confident and comfortable in her abilities and believes she’s already ahead of both her sisters despite the weight of expectation.

But she’s also well aware of the pitfalls ahead, having seen Alyssa and Gisele occasionally stumble into them.

“Yeah, it is a lot of pressure but I feel like we just had different paths,” she said. “They didn’t really know they were going to do soccer. They didn’t know that was their sport. But I feel like that path was set for me.

“It was just like I grew faster. I kind of took the understanding of what they were doing, and then I did it a little faster.”

There are other differences as well. Gisele is a defender and Alyssa a forward, but Zoe plays in the midfield. And while it was sometimes difficult to get anything more than a giggle from Alyssa in an interview even after she turned pro, Zoe already gives complete, thoughtful answers to most questions.

Zoe’s game is also different; while Alyssa and Gisele are both exceptionally fast, Zoe relies more on her skill.

“Zoe’s more technical than her sisters at this stage,” her father said. “She’s better on the ball, she has a better understanding of the game. A lot of their game was because of speed. Hers is more thinking, hers is more of the ball on her feet.

“Technically, she’s better and understands the game at this age.”

Gisele, the sister who chauffeurs Zoe to practice in Santa Clarita, agrees. But, she adds, Zoe’s greatest strength may actually be her desire.

“She just has so many great qualities that me and Alyssa don’t have,” she said. “At her age, she wants it way more than we did. She loves soccer with a passion. Me and Alyssa didn’t love it as much as she does.”

And if that passion translates to performance, Zoe will someday join her sisters on the national team. By then she may even be in the driver’s seat.
