With the Chinese Super League transfer window running into February, Fellaini will have plenty of time to consider his options.
Sources close to the Belgian say he has already decided to leave United, with his current deal to expire at the end of this season.
A Fellaini confidant told the Daily Express: "Fellaini will not extend his contract. He has no preference between leaving in January or this summer. But Manchester United will have the last word on what will happen next month.
"He has an offer from China and could leave for the money."
