About time, AC need to get his wages off the bill + the rumours that he's an unsettling element in the dressing room, with him leaking all the dressing room gossip to his missus, I think they'll all be glad to see the back of him.
I don't think Cole is too bad, if he isn't given a ridiculous contract and signing on fee. I can see him as a decent substitute in tired games and probably get a good few games a season out of him with a couple of goals. He's not what he was, but if he was sent on a free with a normal contract, teams like West Ham and QPR could do well with him.
Yeah he could be pretty decent. The only problem is that he's not exactly young and his injury prone as fuck. Mixed with some crazy wages it makes it a slightly stupid transfer for most teams. QPR are pretty stupid to go for him with all the other big wage flops they have.
As for Ba, aside from wages moving to Chelsea is good for Chelsea but probably not so great for him since he will be behind Torres no matter what.
