A nation of 300 millions need to pinch a player from a nation of 300.000. Are USA really that bad?
What stinks about this is that Aron has had his whole football development in Iceland, has Icelandic parents, with the only connection to the USA being born there. He thinks of himself as an Icelander, but picked USA for WC reasons.
It was his choice, U.S. didn't kidnap him. Plenty of players with less claim to "being American" have pulled on the jersey in recent years, we'll accept any player that wants to play for us.
A good player is a good player, regardless of where he's from. I'd snap your hand off for Sigurdsson too.
