It's a whole other issue.
It's not just the coaching, it's the rules and regulation around them.
English teams have been restricted for a long time by how much they can train their academy players at the most crucial points of their development.
I can't remember the exact figures but it's something like we can only train youth players(like 8-15 year olds or something like that) for 6 hours a week. Where as clubs around europe can train their kids as much as they like.
We've also been restricted by the '90 minute rule' which states your youth players have to live within 90 minute travelling distance from your clubs training ground/academy. Again, in places like spain this isn't the case.
The argument can be made that it helps smaller clubs keep their best youth products until they are old enough to get a decent fee for them, which can be crucial for smaller clubs in helping them simply keep afloat as a business and not folding in on themselves. But on the other hand these promising youngsters at the smaller clubs will be seriously hindered in their development without the best facilities/coaching. Which in the bigger picture doesn't help the national team, we're robbed of what with these best facilities and coaches, could have been a world class player.
The good news is clubs like Man Utd have lead the charge to get these rules changed, Ferguson has spoken about it on a few occasions. I'm almost certain the 90 minute rules is definitely being abolished, not entirely sure on the training time allowed etc.
fukk you small clubs, United are gonna rob your 10 year olds and make them world class. La Masia level stuff it will be, get ready world
