Europe's domestic football leagues, alongside the global players' union Fifpro, have formally lodged a complaint against FIFA, accusing the organization of "abusive and anti-competitive" practices regarding the management of the sport's match calendar. La Liga president Javier Tebas described the day as "one of the most important in football," emphasizing the significance of this collective action. The complaint highlights concerns over FIFA's expansion of the match schedule, which the leagues and Fifpro argue jeopardizes player welfare and the integrity of domestic competitions. They specifically pointed to the upcoming enlarged 2026 World Cup and the newly formatted Club World Cup set to occur next summer as key issues. The complaint was submitted to the European Commission on Monday morning, which will now determine whether to initiate formal proceedings against FIFA, the governing body of football worldwide.
