Can mention quite a few, but most are quite well known, will mention one who isnt prolly, Eden Hazard. Gives me reason to sparingly tune into Ligue 1 games this season. Been on my radar since the U-17 euro of 2007.
His game against Lyon earlier this month was quite nice:
Yeah, as I said, there some very obvious cases, Giovinco, Rossi, Pato (latter two scoring for fun for their teams) etc.
But really, from the really young ones mentionned so far, I get the wow factor the most from Wilshire, he just oozes class with every touch. Really rare youngster, especially as an english player (Not to demean, but he looks very un-english as a player).
Thiago, Gai, Bojan, Keko, Camacho all have bucketloads of talent. These guys impressed me a lot in youth tourneys which of course doesn't mean they'll set the world alight. The potential is definitely there though.
Camacho, meh, he hasn't really impressed me, to say wow. Bojan, blah, he won't succeed at Barcelona, he is wasted on the left side of the trident, or right for that matter. He doesn't nearly have the presence or the ability to be the focal point of the attack, especially at Barca, still very young, but i don't feel he will make it there. Giuseppe Rossi, if you compare to the players mentioned, is alot older, still a great player, and i have high hopes for him, not sure if he will be elite, but still very good.
Danny Welbeck (will definitely become world class)
The only player younger than 20 right now that I've seen who's making it dreadfully obvious that he'll be a superstar the same way we all thought Messi, Aguero, Ronaldo etc would explode is Pato.
That's in terms of attacking players. In terms of defensive players that I've seen, I'm lucky enough to watch Santon every week and he's making it dreadfully obvious he'll be around for a very long time as well.
Not forgetting the likes of Pepper, Rodwell, Baxter, Moses, Bostock etc. the next generation seems to be the most talented we've had in years, sadly I doubt they will be developed or managed properly.
