​The ​Premier League have officially confirmed the opening and closing dates and times of the January ​transfer window during which clubs can conduct their business.

The window will open on Wednesday 1 January and close at 23:00 UK time (4:30am India time) on Friday 31 January 2020. Furthermore, it has also been confirmed that Premier League clubs will be given an extension to finalise their 25-man squad for the second half of the campaign.

Premier League's ​official website reveal that under normal circumstances, clubs need to register their final squad for the rest of the campaign the day after the ​January transfer window closes, but because Deadline Day is the day before a round of Premier League fixtures, the deadline for submission of final squad lists will be on Wednesday 5 February 2020.

The Premier League statement said, "New players signed on 1-2 January will not be eligible for 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."

The statement continued, "Clubs completing deals late on Deadline Day, 31 January, will be able to submit a Deal Sheet between 21:00-23:00 GMT. 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."

With Liverpool racing towards their first ever Premier League title and their 19th domestic league title, it will be intriguing to see if other title challengers dive into the transfer market to strengthen their squads for the second half of the season.
