Older one's first:

I have no doubt Raheem Sterling will become a world class footballer after securing his move to Man City. With all the nonsense gone away he can finally focus on his football, and hopefully start producing the results he should be for England.

Harry Kane will struggle to achieve success similar to that of last season, don't get me wrong he'll score goals, and a decent few of them. However him continuing this form just seems very unlikely.

Ross Barkley needs to get away from Everton or dig deeper for that form we all know he's capable of hitting, he's perfect at his best which can't be said for many players, especially at 21.

I really can't make a proper comment on Luke Shaw because all my manc mates say he's doing alright and it's just injuries that are harboring his progress, but if Shaw manages to hit a decent run of form i'm sure Baines will be given a goodbye in a year or two.

Alex Oxlade-Chamberlain is one of my favorite English talents, truly defines explosive power. As long as Arsenal keep him up to the challenge and keep developing him he could be one of England's biggest players in years to come.

Saido Berahino is an interesting one, i'm unsure whether he's capable of swerving the laddish behavior and dedicating his life to football. If he's willing to he could become a world class player, it's very obvious he has a natural talent and great instinct, wish he'd go to a big club (no offence WBA fans) for that eye opening realisation that he could be a part of the worlds best.

John Stones is going to be an absolute machine, there's no need for any explanation, just watch him when you can, he's 21 years old as is as refined as much as some of the top premier league defenders.

I'll post another comment with the actual future talents (16-20)
