Nope i mean exciting as in having the potential to be really good players.
Here are the young players out of the list Marcello posted:
Goalkeepers: Consigli, Mirante
I think we can agree that there's nothing exciting there.
Fullbacks: Antonini, De Ceglie, De Silvestri, Santon
The first two are average players that probably won't be playing for their respective clubs for a long time. Both had their chances, both showed they're not up to par
De Silvestri has always been overrated, ever since he was at Lazio, then he was benched by Lichtsteiner, and now he's benched by Commotto of all people at Fiorentina. Another player, i wouldn't be excited about.
Santon does have the potential to turn into a good player though.
Centerbacks: Ranocchia
Looks like he could be a good defender, he hasn't proven much yet, as he was injured for a long time last season, though admittedly he has looked impressive whenever i've seen him.
Midfielders: Poli, Candreva
Poli is a good player, though i personally don't see where all the hype is coming from. He's nothing more than a good player for small clubs imo. I don't think he'll turn out to be any Pirlo.
Candreva, we all saw him with Juventus last season, he was somewhat decent, but not a player one would expect to develop into anything special. I don't think he'll ever be good enough for any of Italy's top clubs.
Strikers: Lanzafame, Paloschi, Balotelli, Macheda:
The first two
Balotelli could turn out to be a world class player if he gets the right guidance and does something about his temperament and attitude.
Macheda: He's had limited time at United, did very well in his first few appearances two seasons ago, but didn't impress much in the limited few chances he had last season. I don't hold that against him though, as he set the bar rather highly in his first season and was consequently under a lot of pressure to emulate his feats from two seasons ago. I do think he has the potential to turn into a real goalscorer though, a lot depends on his development under purple face
All in all, i don't think there's a lot of promise there.
