The Frenchman recently rocked the Hammers by saying that he no longer wanted to play for the club, but West Ham are not keen to sell their star man.
The club's vice-chairman, Karren Brady insists that she wouldn't sell the player for any price, but the club may be left with no option if he continues to show a bad attitude.
"Personally I would not sell him for any price," she wrote in her column for the 'Sun'.
"We have already made him our highest paid player but there has been plenty of evidence recently of his lost motivation.
"We will carry on trying to keep him, of course, but his attitude will affect the whole team unless it changes radically".
She added: "With this attitude I suppose that probably sooner rather than later he will be on his way".
