From what I have heard he is one of those players who is supremely talented but who just CBA to train. Hence his injury problems, he is never fit enough and has to push himself in games and his body can't cope.
Given the fact he hasn't had a decent season since his Chelsea days, and his no doubt ridiculous wage demands (plus his age), I wouldn't go near him. Add in the issues of his attitude and the fact he'd hardly help squad togetherness and …….why would you!.?
He wasn't exactly famed for hsi work rate in his Chelsea days, add a few years onto his age, and a few million in his bank account and he's very similar to Ronaldo, albeit a fee yrs younger, not as good at his peak, and a **** tonne cheaper.
