Aha let me see , comparing Ireland and Poland .
I don't know much about Germans playing for Poland over the years.
Let's look at some possible Poles who have played for the Fatherland.
Well Germans had Hans Tilowski ,Jurgen Grabowski and Pierre Littbarski(Polish Surnames) playing for them over the years. Probably a few in more recent times but they have slipped my mind.
English internationals of the past have included ,South African Colin Viljoen
Jamaican John Barnes ;Welshmen Rob Jones and Michael Owen , and Graeme Le Saux who was entitled to French citizenship.
They have 49 million of a population to choose from as opposed to less than 4 million. English internationals in Rugby Welshman Dewi Morris Irishman Kyran Bracken and don't get me started on their cricket team.
If anyone wants to have a go about our football team, the English cannot frigging talk !
At least our Irish internationals qualify under eligibility rules for one of our passports.
