Due to an additional FIFA Club World Cup Registration Period introduced ahead of the start of the FIFA Club World Cup, the EFL and its Clubs have agreed that the summer transfer window shall operate for an additional ten-day period from Sunday 1 June 2025 to 19:00 on Tuesday 10 June 2025. This is due to the transfer window being unable to exceed a total of 89 days.
