There's no problem on the field for the reigning world champions, but off the field is another story. Five members of the U.S. women's national team have filed a federal complaint charging U.S. Soccer with wage discrimination, according to The New York Times

The players involved are Carli Lloyd, Becky Sauerbrunn, Alex Morgan, Megan Rapinoe and Hope Solo. 

From The New York Times:

In their complaint — which was submitted to the Equal Employment Opportunity Commission, the federal agency that enforces civil rights laws against workplace discrimination, on Wednesday — the players requested an investigation of U.S. Soccer. 

The group's lawyer, Jeffrey Kessler, said in a statement according to The New York Times, that the women's national team makes as little as 40 percent of what the men's national team members do. 

“The numbers speak for themselves,” Solo said in the statement. “We are the best in the world, have three World Cup championships, four Olympic championships and the USMNT get paid more to just show up than we get paid to win major championships."

“We have been quite patient over the years with the belief that the federation would do the right thing and compensate us fairly,” Lloyd said in the statement. 

U.S. soccer responded:

The USWNT reportedly received $2 million for winning the last World Cup. The Germany men's team, who beat Argentina in the 2014 World Cup final, got $35 million. 

And all this after the women brought in almost $20 million more than the USMNT last year.
