Da.
Our youth players (some) have potential and they should get their chance eventually. But it's our board that knows if they'll make it or not. It's not Secco, those mistakes barely ever happen. You can't say we won Primavera and that our team is greatness. It's not just potential that makes you a world class player.
We're not doing anything strange here even if we do sign him. Kaka signed for Milan, Pato went there as well. Real bough kids and plans to buy more. Messi to Barca, and now even some 13yo kid went there as well. There are many examples but I should add Cristiano too, a player who's price went from 7 to 97mln euros in 4 years time. I'm not saying we're getting new Ronaldo, but there are chances you'll be getting some player that can develop into top star. We have only Marchisio so far, I hope he improves more but that is nothing.
Inter plays Santon (rarely) and Balotelli. Roma doesn't have anyone good (they lost good player, he went to Manure, or they just stole him to be more precise), Milan doesn't have anyone. It's not like their youth teams suck, and even if they do, they should be some players. But they also keep signing new guys. Palermo's school suck as well? Because I see them getting Hernandez and Pastore's.
If anything, we're a bad club when it comes to buying new raising stars and hopefully we'll start doing something new. Udinese made many good players with no money, which secured them many points and what made their profit in the end. Players like Sanchez and Asamoah come to mind, the latter one costs now a lot while he was bought for peanuts. Porto made tons of cash when they found new stars. Pepe was bought for nothing and he was sold for over 30mln euros, Hulk was found in Japan and there are tons and tons of examples.
The only mistake we're making here is Giovinco. We are not the only team who is doing this. There are not many players where you'll see "Ah, he's from our youth school". Hell, one out of 1000 comes out like that. De Rossi in Roma was a big one, yet that happens almost never. I'd really like to give some of our players shot, I'm not against that. I want to see Immobile. Or some other player. If they go somewhere, it doesn't mean we ruined those. It only means they are not good enough. If they are good, they will sign for a top club, but instead we'll see them go to Empoli, Catania etc.
This or any other move like this can only make us big. There is a risk, there is always a risk. But it's chances you can't miss (I'm not taking this directly at this guy we're after).
