Listen.

United have TRIED English only players. Our 2004-2006 academy was 80% english with such players as Ritchie Jones, Kieron Lee, Ryan Shawcross, Tom Heaton, Luke Steele, David Jones etc etc. They were bollox.

Our Academy now is probably 70% English, most of whom will be sold to lower league clubs. You can make all the rules you want but the talent is just not there in abundance. You also have this insane rule in England that academy players must live within a certain distance to the ground.
