Hope Solo, the former star goalkeeper of the U.S. women’s soccer team, says in a legal motion she should be allowed to participate in an upcoming mediation for the team’s pay-discrimination lawsuit against the U.S. Soccer Federation—in part, Solo says, because she fears her former teammates will “surrender” if she is not included.

All 28 members of the USWNT player pool sued U.S. Soccer on March 8, alleging that the federation illegally paid them less than the U.S. men’s national team despite the women having the same job responsibilities and higher achievement. Earlier this month the team won its second consecutive World Cup and fourth overall. The men’s team hasn’t won a World Cup and failed to qualify for the 2018 tournament.

The players and U.S. Soccer said in June that they planned to pursue mediation after the World Cup, which ended July 7.

Solo sued U.S. Soccer more than six months before her former teammates, in August 2018. The two lawsuits made similar allegations.

Solo’s motion, filed Monday in the Northern District of California, alleges that Solo’s claims for equal pay will be compromised if she’s excluded from the team’s mediation. During previous collective-bargaining negotiations with U.S. Soccer, the USWNT succumbed to pressure and “backed-down, kept their jobs, took the unequal compensation, and forfeited the prospects for Equal Pay,” the motion alleges.
