Sunderland are willing to sell Lamine Kone this month.
The Sun says boss David Moyes is willing to sell Kone to raise funds for new players.
Kone, 27, signed a new deal in September after settling a pay row with the Black Cats.
But Moyes could still move the Ivorian out if he gets around £15million.
Moyes is checking out possible replacements at home and abroad and could do a one-in-one-out move if he finds the right defender.
West Ham and Crystal Palace like Kone but are put off by the big asking price.
