According to The Times, in a concerted effort to challenge FIFA's plans, Fifpro and the World Leagues organisation have sent a strongly worded letter to the governing body of world football, expressing their concerns about the schedule of the expanded edition of the Club World Cup that is slated to take place in the United States in June 2025, with prominent European clubs such as Manchester City, Real Madrid, and Chelsea participating alongside other top teams from around the world.
They argue that FIFA's decision to expand the Club World Cup and its overall match calendar has adverse consequences, including "economic harm" to domestic leagues and a "significant injury risk" to players. Additionally, they accuse FIFA of prioritising its commercial interests over the welfare of players and the integrity of the sport.
