The response I would give to that is that if young English talent is so good, why isn't it being snapped up in other European leagues where they can get game time and improve the quality of their leagues? Unfortunately English talent simply does not have the technical skills or quality that othe European countries do, due to the fact we teach them wrong. How many top stars have been told that they weren't going to make it because they were too small? Attitude and training shift needed big time.
I agree to a point but I would say that most English lads probably don't want to move abroad at 16-18, particularly to largely inferior leagues. Spain and Germany have enough youngsters coming through not to bother with ours so they'd be going to places like France and Belgium. That's probably championship standard at best (save for PSG) so they may as well stay here. Youngsters get plenty of chances in the lower leagues. It's really only the top end of the P.L where it's been a bigger issue.
But I agree that we don't place enough emphasis on the more technical aspects of the game from a young age. But somewhere like Hollland does and they've got a very poor international team at the moment and not many good players coming through. Very tricky subject.
