Giovinco didn't become this famous suddenly, Didier didn't use him for nothing, and specially at a time when we needed to score a goal. Sure he is not a star yet, but 15 minutes can be enough sometimes to see a player's talent.
it's not the only that dribbling or the pass that made me like him, I saw the hunger in him, he was running like a crazy to prove himself, to be part of this team, that's a plus next to his skills!!
