Chelsea bought Torres and have Drogba so obviously won't be after him.
On the contrary, I think that if he was to go to another PL club, Chelsea would be the obvious choice. Drogba is probably in his last season at Chelsea. He's 33, and Anelka's 32 - and also possibly in his last season at Chelsea.
If it's true he's will to stay in England, then it wouldn't surprise me one bit to see him at Chelsea either in January or the summer.
