Having good training schedules and coaches is definitely a plus but wonderkids can still develop into great talent even with average coaches. It really comes down to managing them.
From my experience depending on your tactics and how you play them their stats grow in the areas their position specializes in. For example if a player you coach can play as both a forward and attacking mid but you choose to play him as a playmaker in midfield, his stats in technique and passing are more likely to increase than his finishing. Also you should have more experienced players in the squad who perform the same role mentor the younger player. Again, for example you are training a midfield playmaker then you should assign an older midfield playmaker in the squad to tutor your wonderkid.
If you feel they are old enough or good enough to jump out of the youth squad then you have to look into loaning them out and giving them as much playtime as possible. From my experience this age would be around 16-18. Once they are good enough to be a backup to the first team, start integrating them into the squad. Maybe 10-20 appearances a season. Hope that helps.
