But for every Kezman, there is a van Nistelrooy, Bergkamp, VDV, van Persie.
Sorry I must have missed the bit where Bergkamp proved himself at Inter and VDV proved himself in Germany and Spain despite opportunity.
Van Persie didn't do anything in Holland.
Ruud is the obvious exception, but another telling thing hear is, those players are dutch, and coming to England is easier for them.
