Soccer star Alex Morgan is an Olympic gold medalist, Women's World Cup winner, and one of Time magazine's 100 most influential people of 2019 but her biggest challenge is the fight for pay parity in the sport she loves to play.

Morgan and her teammates are underpaid compared to the U.S. men's national soccer team even though the women consistently outperform them in terms of victories, domestic viewership numbers per SportsMediaWatch.com, and popularity per The Nation's report.

US WOMEN'S SOCCER STAR CRYSTAL DUNN READY TO BRING TEAM ANOTHER WORLD CUP GLORY

The biggest disparity is the number of World Cup trophies - three for the women's team (1991, 1999, 2015) to none for the men's team. The men's team didn't qualify for the 2018 Men's World Cup and best they've ever placed in the tournament is third in 1930.

On the red carpet at the Time100 gala in New York City, Morgan spoke to Fox News about her and her teammates' fight for pay parity and what it was like seeing actresses from Hollywood show up in support of them.

"It was awesome," she said. "I never imagined them coming to a soccer game and I've watched all of them in movies and TV. They have such a huge influence and they've pulled in so many directions so it meant a lot to us for them to attend our game."

FROM SUPER SUB TO SUPERSTAR: ALEX MORGAN HAS COME A LONG WAY SINCE HER 1ST WORLD CUP IN 2011

On April 7, celebrities including Jennifer Garner, Natalie Portman, Uzo Aduba, Jessica Chastain and Eva Longoria all attended the U.S. women’s national team player's event in Los Angeles to stand in solidarity with the soccer stars.

"So the US women’s team is the best in the world and the men’s team gets paid more? #TimesUpPayUp,” Chastain wrote on social media at that time.

In March 2016, five top players from the women's team -- Hope Solo, Carli Lloyd, Becky Sauerbrunn, Alex Morgan, and Megan Rapinoe -- filed a federal wage complaint in which alleged they were victims of pay discrimination.

“The numbers speak for themselves,” said Solo, the team's goalkeeper at the time. “We are the best in the world, have three World Cup championships, four Olympic championships.”

In March 2019, 28 members of the women's soccer team filed a gender discrimination lawsuit calling out issues (again) with compensation, working conditions, medical treatment received.

This summer the team is heading to France for the 2019 Women's World Cup to defend their title as champions.
