Charlie,

in German Football we have the “Ausländerregelung” or the Foreigners Law which demands that every professional German Team must have at least eight Players that were either born in Germany or trained in a German team between the age of 15 and 21 without interruption. The Bundesliga has 61 percent German Players.
.

Sounds like what we should have here Peter. Although I don’t see it happening.

I remember a game being played between Arsenal and Chelsea (I seem to remember). Where only one
of the players on the pitch was eligible to play for England.
