Chamakh has been linked with the French club in recent days.
"Chamakh? He knows when he wants too, he can return to Bordeaux - but he is happy in London," he told Le 10 Sport.
"I see he is not on the score sheet and the media do not talk about him but he says nothing.
"Salaries are different in England, but last December I sent him a message to tell him that if your not happy in London, come home, and that message is still relevant today."
