Quaresma often has a bad haircut.
That said, I've been following the guy very closely in the Portuguese SuperLiga and on the Portugal NT for several years. A couple years ago, IMO, he was at his peak -- physically and mentally. He's still young, but something mentally happened to the guy in the past couple of years. Ego. Discontent with his club. Something. Since then, he's been a little more headcase than he's been a performer, IMO -- at least to the extent that he hasn't lived up to his abilities in a couple of years.
Perhaps Mourinho is just the guy to change that, although I would say Inter is the wrong environment for that. As such, Quaresma's signing to me seems like a pretty big gamble for Inter. We have the potential for a 2009 Bidone d'Oro in him, and I'm serious about that. Yet Mourinho could make him into one of the premier wingers in Serie A next year. Could go either way, really.
