The French midfielder has been linked with a move to England.
He told L'Equipe: "I don't know what will happen.
"I have everything here. There is real quality of life, we play in the Champions League and I have a very good relationship with the coach.
"I don't know what my future will hold, but every day I have fun going into training.
"In a perfect world I would like to stay, but I appreciate the club could sell me for financial reasons and I wouldn't really have any choice."
