Groups B, D & G look the most interesting to me.
I'm not saying he'll be as great as those two, but in the scope of today's young Italian talent, he has the most potential to be a great player. Balotelli could be but his skull is too thick, El Shaarawy is too one dimensional, and none of the others (Destro, Borini, Immobile etc) have impressed me as much. There's Berardi but he's too young to be considered in this generation.
It's not really fair to set the bar so high when players such as Del Piero & Totti are extremely rare.
