The French side are now rumoured to be willing to pay £15million for the striker, who will still have a year to run on his contract come the summer.
The 29-year old, who is never far from controversy, was recently arrested on suspicion of driving whilst disqualified.
The Express claim: "It is unlikely that City would be willing to put up too much of a fight to keep the forward, who has served the club since 2009".
