That is excluding the cap-tied rule. Which player in the history of the game can represent the most countries? Sean Dundee: Germany, Scotland, South Africa. Unsure about England. Kuranyi: Germany, Brazil, Panama, Hungary(?).
It's complicated, but there's a fair number of players who are eligible to play for England, Scoland, Wales, Northern Ireland plus one or more othe rcountries. For example I'd guess Robbie Earnshaw (who is now cap-tied to Wales), would of been eligble to play for Wales, England, Northern Ireland, Scotland and Zambia, possibly even Malawi too.
i thought about opening a thread like this... but it always starts with arguments over klose or podolski or deco or someone who plays for a country they weren't born in, and that opens the flame fest.
