Top Winston & Strawn antitrust lawyer Jeffery Kessler is back in the sports industry spotlight this week, after a group of leading U.S. women’s soccer players accused the sport’s governing body of sex bias.

As widely reported on Thursday, Kessler is representing five prominent members of the U.S. women’s national soccer team—Alex Morgan, Carli Lloyd, Hope Solo, Megan Rapinoe and Rebecca Sauerbrunn—in a wage discrimination case filed at the U.S. Equal Employment Opportunity Commission. The EEOC filing alleges that female players are paid substantially less than members of the U.S. men’s soccer team, despite the women’s exemplary record on the international stage, which includes winning the most recent World Cup in July.
