Personally I think he would just be coming for the money, at his age etc he can't really have too many more ambitions to fullfill
He's got enough money I think.
In terms of ambition, he has spent his whole career in Italy watching the Premier League become the best league in the world. Maybe he views this as a chance to play in the Premier League for a couple of seasons and to show what a great player he is to everyone, on the biggest stage.
And he's only got one Champions League winners' medal.
