I can kind of see why they're trying this but it's not going to work.
Plus i think one of the criteria states a certain ammount of players brought on by the club from an early age (can't remember the exact wording and don't have time to look now), so you will just see teams bringing in foreign kids and putting them in their academies like some teams already do now, so it's still not going to help the home countries kids to develope.
Anyway, if you're good enough to make it as a footballer, it doesn't matter where you're from, i think the reason why our countries players are lacking is due to our crap training structure and playing football on full size pitches with full sized balls from an early age.
