That will be a great day, but, nevertheless, unless contacts can be offered to those under 17 the best talents will still be nabbed by English clubs.
Who can blame those to youngsters for wanting the opportunity of joining great clubs: not to mention the financial benifits on offer.
The great thing about this rule is that less and less foreigners will move abroad to other nations. Right now an italian, french or spanish youngters know that they have a real chance to play in england in one of the top teams ( they have the same chance as any other english youngsters in that team if not a bigger chance than them).
Once that rule is introduced, those youngsters have to fight with other allready established foreign players for the 5 spots in each team (that is an almost impossible mission unless that youngster is Messi or a really special talent).
Clubs like united, pool, chelski and arsenal being the wealthiest clubs out there they won't sign a promising foreign youngster to take that limited spots. They rather keep those spots to a really highly rated foreign player.
So instead of signing 15-20 promising foreign youngters in their team (thats whats happening right now there). They'll spend their cash on highly rated allready established foreigners Plus they'll spend their cash on their domestic academies so that they can prepare the next generation of english players (which is a really hard task but good luck for them).
The 6+5 rule will fix even snaping the youngsters from other countries and it will give a more balanced competitions between european clubs in europe....
