The 32-year-old is now free to leave Stamford Bridge because his contract has expired and a return to the French League or a move to Brazilian club is likely.
He said: "I had a problem to sort out with certain people. It's done. Now, I'm free. I'm going to be able to play again next season. I've been preparing all season long.
"I've let people speak. I'm patient and very determined. I'll be back next season. I already know where, but I'm not saying anything for the moment. Anything is possible."
