The January 2020 transfer window is set to open on New Year's Day with the deadlines set to be on Friday 31st January at 2:00 AM EAT.
Premier League clubs will have until midnight on Deadline Day to complete the information needed by FIFA's Transfer Matching System to apply for international clearance for new signings. Any player signed on 1/2 January will not be eligible to feature in the Matchweek 21 but they can be made available for the following Matchweeks as clubs are permitted to make changes to their squad lists throughout the January window.
Any deal completed late on the Deadline Day the club should submit a Deal Sheet between 12:00 AM and 2:00 AM EAT.
Squad lists Deadline
Normally Premier League clubs will need to register their final 25-man squad for the rest of the campaign the day after the transfer window closes, but because Deadline Day is the day before a round of fixtures, the deadline for submission of final squad lists will be 5:00 PM EAT on Wednesday 5 February 2020.
