Chelsea January transfers and net spend: Every confirmed signing and sale for the West London side in 2026 winter window

After committing to another summer of heavy investment that saw the high-profile arrivals of Alejandro Garnacho, Joao Pedro and Jamie Gittens, Chelsea have experienced a 2025-26 campaign that has fluctuated between global glory and domestic frustration.

While the Blues started the season inspired by their FIFA Club World Cup victory and the emergence of teenage star Estevao Willian, a recent decline in form has led to familiar doubts about the consistency of an expensive squad.

The West Londoners currently find themselves fighting to stay in the top-four conversation after a difficult December period that yielded just one win in seven league outings, leaving them significantly off the pace of the title-chasing pack.

Having offloaded the likes of Christopher Nkunku and Noni Madueke, it remains to be seen whether the hierarchy will sanction further mid-season spending to address a growing defensive vulnerability or if the focus will shift to further streamlining a roster that remains one of the largest in the division.

Here, Sports Mole rounds up all of Chelsea's confirmed ins and outs during the 2026 January transfer window, as well as looking at their net spend and latest transfer rumours.
