English midfielder Jay Matete, 24, is included in Sunderland's 2026 free agent list. Sunderland need to decide which players can develop into important options for the future and sort out their contract situations quickly. For the other players, they should look to do their best to get rid of them during the January transfer window, so that they can recoup some money from their departures instead of losing them for free. His market value is currently estimated by Transfermarkt at €400k.
