USWNT fans got their first look at Alyssa Thompson on Friday as the 17-year-old made her national team debut in a 2-1 friendly loss to England at Wembley Stadium.

Thompson entered the game at the 83-minute mark, subbing in for Megan Rapinoe.

Following the game, Rapinoe joked about the 20-year age gap between the veteran and the teenager.

“I can literally be her mom and like, not her team mom,” she told Meg Linehan of The Athletic. “I asked her a couple times, “Are you just like, What the f— is going on?’ You’re playing in this massive game. It’s such a young age.”

Thompson is the youngest player to earn a call-up for a full national team camp since Sophia Smith was selected in April 2017 as a 16-year-old.

When the roster was announced on Sept. 29, coach Vlatko Andonovski expressed excitement for her potential, and for the youngster to experience playing at the highest level.

“This is the first experience for her,” he said. “This is something that she shouldn’t even worry about. I think it’s a great experience, great exposure for her. And it’s a good experience for us to have the opportunity to work with her. What happens from there, we will see.”

The forward previously played for the U.S. youth national team in August during the U-20 Women’s World Cup. Her younger sister, Gisele, is gearing up to represent the U.S. at the U-17 Women’s World Cup in India this month.

Thompson, a high-school senior in Studio City, Calif., is signed to play collegiate soccer at Stanford next season.
