Most common real players in T11

[David Burke]

i've seen a few teams with a full squad of real players mostly they are spanish users.... i've managed to get Tiago Silva and Christiano Ronaldo and i've had a few bidding wars for Messi, Giggs, David Luiz, Juan Mata and a couple of others, been wondering tho if there is anyway to make our youth facility better so we get get young reals players?
