West Ham January transfers and net spend: Every confirmed signing and sale for Thomas Frank's side in 2026 winter window

In disarray on and off the field, West Ham United's Premier League status looks set to be under serious threat in the second half of the 2025-26 season, despite the best efforts of former Nottingham Forest and Tottenham Hotspur boss Nuno Espirito Santo.

Reliable captain Jarrod Bowen is doing all he can to keep the Irons afloat, as are summer signings Mateus Fernandes and El Hadji Malick Diouf, but additional reinforcements must be sought in January for the upcoming relegation dogfight.

The Hammers suffered a major blow as they lost Lucas Paqueta, who returned to Brazil with Flamengo, after a deal in the region of £36.36m was agreed. 

The former Lyon midfielder got disillusioned with life at the London Stadium, a consequence of West Ham's familiar on-field struggles and the long-running FA investigation into his alleged spot-fixing offences, which he was cleared of.

The 28-year-old's fortunes may improve now that West Ham have added attacking duo Taty Castellanos and Pablo Felipe to their ranks, but if the London club's recent form is anything to go by, the powers-that-be must splash the cash further to avoid a Championship campaign in 2026-27.

West Ham also secured the signing of Chelsea defender Axel Disasi, who joined on loan for the rest of the season with the Hammers not having the obligation to sign him permanently. 

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