Not talking about being unconcerned, but you are skiping a major step, when you assume pretty much EVERYONE are good enough to play for the senior team, pretty automatic, hence they are being RUINED being on loan/co-owned and not being with the senior team instead, as I said, skipping a major step.
I very much like them to play for our team if they are good enough, and preferly get more chance to show they can, but this is RARE for a reason, besides italian footballs bit pessimistic approach to younger players, its also because very few of these players are good enough.
All I'm saying is its a counterproductive attitude to have, loan-co-owns being bad automatically makes the assumption that these youth players are somehow all automatically good enough to play for the A team. I dont like how few of them get a chance (as I said already with italian footie's cautious approach being bit too rigid too often), but I also dont like every youngster being assumed to be someone who we are wasting on loan (I used to hear ridiclous moanings about frigging Volpato, the next Vieri), instead of simply taking the time to realize wether they are good enough or not, and that also happens indirectly through loans. Because the Senior team doesnt have time to, or doesnt deem them good enough.
There are Paro's, Rocchi's, Cassani's, Nocerino's, Loria's, Milanetto's and so on with the long long long list of youth products who are merely average players, producing Serie A level players in itself its an acheivement. Let alone those worthy of the requirements of Juve. Giovinco and Marchisio are a rarity for a reason. Even more so with how rare it is big legends like Boniperti, Bettega, Combi etc coming through your youth academy.
