Five of the biggest names on the U.S. womens national soccer team roster filed a complaint against the U.S. Soccer Federation on Wednesday, demanding equal pay for equal work and calling for an investigation of what they believe to be U.S. Soccers discriminatory wage practices.

The complaint comes less than nine months after the womens team hoisted up the gold trophy at the 2015 World Cup, a feat the mens team has never accomplished.

While Carli Lloyd, Alex Morgan, Megan Rapinoe, Becky Sauerbrunn and Hope Solo were the players who actually inked their names onto the filing, they emphasized they were taking action on behalf of the entire national team .

"Every single day we sacrifice just as much as the men. We work just as much," standout forward Morgan explained on NBC's "Today" Thursday morning . "We endure just as much physically and emotionally. Our fans really do appreciate us every day for that. We saw that with the high of last summer. We're really asking, and demanding now, that our federation, and our employer really, step up and appreciate us as well."
