Marseille president Jean-Claude Dassier says Hatem Ben Arfa may leave the club in January if the price is right.
Ben Arfa, 22, was one of the best-rated talents in France but there are questions over his attitude and, after leaving Lyon for the Stade Velodrome in 2008, the winger has failed to fulfil his potential.
The France international had an argument with coach Didier Deschamps in November and appeared certain to leave in the transfer window, but he has since enjoyed a good run of form in the side following an injury to Mamadou Niang.
However, while Dassier admits he would love to see the player seize his chance in the remaining games before the transfer window reopens, he believes the player's attitude could mean he has no future at the club.
"Ben Arfa can benefit from the injury to Niang," he told France Football. "This is his last chance! I have plainly explained this notion.
"Clearly, he is not committed enough physically. He does not do enough for the team, does not sweat enough for the shirt. If that is what Didier thinks, I cannot contradict him.
"I regret this deeply because, as a player, he has what it takes to be a great. Now, if the market is interesting, we will study the offers, so if there is a good option, yes, but he won't leave at any price."
Ben Arfa has been linked with Tottenham and Portsmouth.
