David,
So there is also a lack of ambition, or alternatively a parochialism, amongst young British footballers.

Is it true that English players are turning down offers from abroad, or are they just not good enough to be wanted?

PFR,
big fish small pond syndrome...???

Hardly. The English league id dominated by foreign players. Two thirds! The English players are the small fish in this pond.

I suspect that David is right about the English clubs not identifying skilled young players.They are being failed by the system and England is doomed to perpetual humiliation in internationals because of it.
