To accommodate the 2025 Club World Cup participants, the first transfer window will open earlier than usual, running from Sunday, June 1, to Tuesday, June 10. After a brief closure, it will reopen on Monday, June 16, and will continue as usual until Monday, September 1. The adjustment follows FIFA’s announcement of an interim transfer window last October, designed specifically for clubs participating in the expanded Club World Cup in the United States. This ruling allows teams such as Manchester City and Chelsea to strengthen their squads and extend contracts before the competition begins on June 14.
