Yes thats true, but if you are a young English player then you need to be be given an advantage to progress ahead of others that aren't English, similarly with local ahead of non local, accepting that the talent pool is similar and your aim is for English/local players to succeed.
I think perhaps the dynamic is different at the very top clubs, they scramble to sign those at the very top tier of young talent, there are less of them and there of a premium, but as soon as you look beyond those talented few into perhaps the Championship the development coach could if capable enough find successes nearer home.
But that would then make the Academy recruitment departments redundant.........
But the majority of fans don't care about background. Look at the abuse directed towards JFC, a product of the Academy, here on NSC.
