Like all national teams, the United States is a bit of a stew. Not only does it only feature a handful of players who are teammates at the club level, it also pulls in players from numerous leagues who weren't even raised in the same domestic footballing culture.
The most common influence, though, is MLS which sent 10 players to Brazil. The Seattle Sounders are as well represented as any team, with two players. DeAndre Yedlin and Clint Dempsey will carry the Sounders banner as they prepare to take on Ghana on Monday.
