European Leagues and FIFPro, the global players' union, have jointly filed a formal complaint against FIFA with the European Commission, challenging FIFA's control over the football calendar. This unprecedented legal action, which has been in discussions since July, highlights the growing tension between FIFA and national leagues and players, who argue that the current schedule is unsustainable and poses health risks due to excessive player workloads. The complaint also points out FIFA's unilateral decisions, such as the introduction of a 32-team Club World Cup, which they claim prioritizes FIFA's commercial interests over the welfare of players and the economic interests of leagues. FIFA, however, maintains that the calendar was the result of extensive consultation and is fully compliant with agreements. The move reflects a broader trend of athletes and sports organizations seeking EU intervention to balance the power of governing bodies. This legal challenge comes in the wake of a European court ruling that FIFA's player transfer rules violate EU laws.
