His brother , Antonio, was suppose to be the next big thing too. Nothing of him.
What I've found in my years as a Milan supporter is this: Hyped youngsters be it Di Gennaro, De Zerbi, Piccolo, Donati, Valoti, Albertazzi( just go back to his early pages he was going to be the next Costurcurta), Merkel etc. don't generally turn out to be much.
It's usually ones that don't get much attention that come through. One example was most people raved about De Vito, not many about De Sciglio.
Another was a lot of talk used to be of Michele Piccolo, nothing much of Matri. While you can argue all of Matri's pro's and con's he is of course somewhere, Piccolo who knows?
I hope that's not the case with Mastour and also would be good if Donnarumma comes good.
