Beşiktaş eye January move for West Ham's Mavropanos
The situation
West Ham United find themselves fending off renewed interest from Beşiktaş in Konstantinos Mavropanos, with the Turkish club reportedly plotting a fresh attempt to sign the Greek centre-back when the January window opens. No bid is on the table today, and no window for Super Lig clubs is even open yet, but Beşiktaş are said to be building toward one. West Ham's position, by contrast, has hardened: reports suggest the club is ready to resist any approach, and there is even talk that Mavropanos may need to file a transfer request simply to force the issue.
The reporting
The story so far rests entirely on Sport Witness, which first reported the interest on 27 October 2026 and followed up four days later with the claim about a possible transfer request. No second outlet has corroborated either report. That makes this a single-source story, and a thin one at that, repeated rather than substantiated.
The outlook
With 18 months left on his contract once January arrives, West Ham hold all the leverage here, and nothing forces their hand. For this to move, Beşiktaş would need to table a concrete bid, West Ham would need to soften their stance, and Mavropanos himself may have to escalate matters from his end. As things stand, call it a long shot that depends on several dominoes falling the same way.
The context
Beşiktaş have shown they can spend at this level, having paid €18m for Leandro Trossard and €18m for Emmanuel Agbadou in 2026. Mavropanos himself joined West Ham from Stuttgart for €20m, so a fee in that bracket would not be unusual territory for either club.
What to watch
Watch for any actual bid once the January window opens on 1 January 2027, and for signs of whether West Ham's resistance holds or whether Mavropanos pushes for an exit himself.
