Ten of the U.S. players are veterans of U-20 or U-17 World Cups. The team's eight college players include Notre Dame's Aaron Maund, whose eligibility to represent the USA despite having represented Trinidad & Tobago at the 2007 Under-17 World Cup in South Korea was confirmed by FIFA last week.
FIFA's rules permit a player to change his or her allegiance after participating for one country in an official competition at the youth level.
Goalkeeper Brian Perk, defender Anthony Wallace and in midfielder Bryan Arguez were part of the U.S. team that advanced to the quarterfinals of the 2007 FIFA U-20 World Cup in Canada. That team was also coached by Rongen.
