All leagues have now confirmed their summer transfer window dates.
Clubs in all leagues will still be able to sign players as free agents after the deadline, and as long as they are not officially attached to any club on Thursday, Sept. 1.
The general deadline is Sept. 1 rather than Aug. 31 as there are many games in the Premier League, Serie A and Ligue 1 on Aug. 31.
Deals can be agreed between leagues with different transfer windows. They will be officially completed if or when the signing club's window is open.
Premier League transfer window
The transfer market reopened on Friday, June 10, though most international deals and free transfers did not go through until July 1.
The Premier League will close the transfer window on Thursday, Sept. 1, at 11 p.m. BST / 6 p.m. ET. There is no early closure before the season kicks off
