He said: "The most advanced contact is with Sunderland. Though for some it is not a very big club, bring it on. I know this may be a step and it is my wish.
"I'm very happy in Bordeaux but I’ve expressed my desire to go to England to join the Premier League and discover new challenges.
"Bordeaux made me a more interesting contract offer, at the same wage level as in England. As we say sometimes, though, I just want to leave.
"I have always given everything for the club and I have never cheated. Bordeaux will stay in my heart."
