There are five types of youth player.
1. The 1/100 who was destined to make it right from the start. They are few and far between and I can only remember five players who I saw at youth level who I thought were dead certs (Whiteside, Giggs, Butt, Morrison, Greenwood). All the others were maybe's for one reason or another.
2. Players who show all the potential but develop into very good players a bit later. There are loads of like that including Albiston, Duxbury, Hughes, Scholes, Fletcher, Beckham, Neville, Brown, etc
3. Good solid pro's who form part of a first team squad. Again there are loads of those including P. Neville, O'Shea, Blackmore, Cleverley etc
4. Good players but not at United level (which is one of the highest in the world) and they tend to be part of the 67% who go on to careers elsewhere.
5. The final group are players that just didn't develop and plateaued early...and they tend to leave the game.
In terms of our U/18's and U/23's we definitely don't have any in Group 1 but maybe in Group 2 and 3.
