The 2026 winter transfer window promises to be another busy period, after Premier League clubs spent a record £3 billion ($4 billion) in a summer window that finished with a bang thanks to Liverpool's £125 million ($169 million) signing of Newcastle United striker Alexander Isak.
The figure, estimated by finance company Deloitte, smashed the previous record of £2.36 billion ($3.2 billion) two summers ago.
As ever, clubs in all leagues will still be able to sign players as free agents after the February deadline, as long as they are not officially attached to any club when the window closes.
Deals can be agreed between leagues with transfer windows which are closed. They will be officially completed when the signing club's window is open.
