Callum Wilson is expected to terminate his contract with West Ham in the coming days and become a free agent. O'Neill has said that Wilson is a very fine player, adding that he had heard unofficially that the player might have been going to Leicester City.

Leicester City have made an initial inquiry regarding Wilson. Wilson's name has been discussed internally as Leicester consider experienced attacking options for the remainder of the campaign. However, West Ham and Wilson have not yet received a formal approach.

Leicester City are believed to be the favourites to sign Callum Wilson, who is West Ham's second-highest scorer this season.

Leicester City are considering a move for West Ham United's English striker Callum Wilson, who could be available on a free transfer this month. The 33-year-old has received less playing time at the London club. According to BBC Sport, West Ham are in talks to terminate his contract. Leicester manager Marti Cifuentes is looking to add more attacking options during the January transfer window. Speaking on TalkSPORT, transfer expert Ben Jacobs stated that Leicester are interested in Wilson, but only if he becomes a free agent, as the club is not in a position to pay a transfer fee. Jacobs also noted that there is interest from the Saudi Pro League, with Al-Shabab and possibly Al-Ettifaq monitoring the situation. Wilson has 9 caps and 2 goals for England and has scored 4 goals in 17 Premier League appearances this season. His current market value is €5.00m, according to Transfermarkt.
