Giovinco is a bigger talent then Rossi, who is beyond stellar (and he can be ridicolously effective), but having seen them together in the Azzurrini (and thats why I want us to sign him, their partnership is simply magical), I can say for sure even Rossi's nonna would admit to that. That Rossi is ahead of him in his career, is quite obvious though. But doesnt mean alot.
Yeah he hasnt proven himself yet, but it has little do with him NOT being good enough, I mean, he does what he did in that Lecce game, and then is benched for over 1 month without playing zip? It doesnt have much to do with him proving himself or not, its painstackingly clear enough.
