Here, we take a look at the transfer rules which govern each league in the winter window in January and February 2021.
Clubs are still able to sign players as free agents after the deadline, as long as they are not officially attached to any club when the window closes, which is Feb. 1 in most leagues because Jan. 31 falls on a Sunday.
Premier League transfer deadline
The transfer market will close at 11 p.m. GMT / 6 p.m. ET on Monday, Feb. 1.
