European football leagues and player unions, including the Premier League and FIFPRO Europe, have filed a legal complaint with the European Commission against FIFA, citing an 'unsustainable' and 'saturated' international match calendar. They accuse FIFA of making unilateral decisions that favor its own competitions and commercial interests, harming the economic interests of national leagues and player welfare. The complaint alleges that FIFA's dual role as both a global regulator and competition organizer represents a conflict of interest and breaches EU competition law. This legal action follows a European Court of Justice ruling in December, which found FIFA and UEFA abused their dominant positions in a similar case. FIFA has countered by accusing some leagues of acting out of commercial self-interest and hypocrisy. The ongoing dispute highlights the growing tension over the congested fixture schedules and their impact on players' health.
