Premier League clubs have agreed to open the transfer window early for a 10-day period in June, ahead of the FIFA Club World Cup, before it reopens again on June 16, the league said on Thursday. The decision comes after world football's governing body FIFA decided member associations of participating clubs would have the option of opening an "exceptional registration window" in June before the event begins to sign players. "The window will open early, between Sunday 1 June and Tuesday 10 June, due to an exceptional registration period relating to the FIFA Club World Cup," the Premier League said in a statement. "It will then reopen on Monday 16 June and close on Monday 1 September." The 32-team Club World Cup in the United States runs from June 14 to July 13, with Chelsea and Manchester City the two Premier League teams taking part this year. Last year the summer transfer window was open between June 14 and Aug. 30. The winners of this summer's 32-team Club World Cup will earn up to $125 million, FIFA said on Wednesday.
