Next season, all three European club competitions will be expanded to 36 teams. In a letter addressed to Fifa president Gianni Infantino and general secretary Mattias Grafstrom, seen by BBC Sport, Fifpro and the World Leagues Association say if Fifa extends its own competitions then it should alter others. It also believes the influential European Clubs’ Association backed the Club World Cup plans in a statement in December. Fifpro and the World Leagues Association believe they have already provided Fifa with ample opportunity to address their concerns. The threat of legal action against Fifa comes against a backdrop of Premier League clubs announcing lucrative post and pre-season tours.
