That fee will drop as the years of his contract countdown, and he could eventually leave us for as little as £3.5 million. But that seems unlikely after reading Gallas's recent comments.
Speaking to the BBC, Gallas said "Right now I could see myself being at Chelsea for the rest of my career. If we play every year in the Champions League and win a cup, why not?
"That's asking a lot but we have big ambitions in this Chelsea team. I think that most of this team will be together for a long time.
"I have three years left on my contract. But right now my agent is already talking to Chelsea about a new one. We may extend it for two or three years, I am not sure. But I am very happy to stay at Chelsea."
And Gallas admitted that his recent appearances for France have also made him realise that it wouldn't have happened unless we made a move for him: "I have just been picked for the France team again. This has only happened because I am at Chelsea, so why would I want to leave?
"When I arrived there were clauses in my contract because I was not sure how it would work out. It was not easy coming into a new country. Now I am quite happy if they are taken out."
What are you waiting for Chelsea- get those damn clauses out of his contract!
