With no real creativity in Italy (Pirlo, although his recent form is quite good, is predictable on the world stage; hence his creativity is in question) Cassano MUST be chosen. He's a game breaker; plain and simple he'll make things out of nothing and feed whoever are the out-n-out strikers. My opinion, he should play alongside clubmate Pazzini in the Starting XI. They've proven that they can play together to perfection (Samp only struggles because they have nobody to give them the ball). Cassano is magical.
...And yes, I am biased since I'm from Bari, but nonetheless, his talent cannot be ignored. Two yellows last year and and three this year. His temperment has improved along with his work ethic (remember he turned up a week early to training...and he WASN'T fat??). There is no reason for his exclusion.
But it won't happen. Lippi is too stuborn and unlike Donadoni, he won't buckle to the demands of the fickle Italian media.
