[U.S. UNDER-23 MEN] Six German-Americans, three players who have won senior national team caps and Josh Gatt, who helped Molde win the 2011 Norwegian league title, are among the 20 European-based players called up for the U.S. under-23 national team camp to be held Nov. 7-16 at the Sportschule Wedau, a German sports school in Duisburg, where the players will train and stay.

U.S. under-23 head coach Caleb Porter, who will miss the camp because of his commitments with the University of Akron, named 31 players to the camp roster. More players may be added based on the results of the MLS playoffs.

U.S. Soccer youth technical director Claudio Reyna will direct the U-23s, while U.S. Under-20 head coach Tab Ramos will lead his age group of players at the camp.

Three players have senior caps: Norwegian-bred Mixx Diskerud has two caps and Gale Agbossoumonde and Sean Johnson each have one.

The six German-Americans follow in the footsteps of four German-Americans called into the senior national team in the last year. The players called into the national team include Terrence Boyd, who recently suited up for Bundesliga champion Borussia Dortmund for a league game.

Six other players who were bred in the USA but are now based in Germany were called up. They include Bobby Wood, who has played for 1860 Munich's first team.

The one Mexican-based player is Joe Corona, who plays for Tijuana and recently was called up for Mexico's U-22 national team but was not picked to go to the Pan-American Games Mexico won.

Gatt, who was recently injured, made immediate contributions in his first full season in Europe at Molde.

Two players -- Perry Kitchen and Zarek Valentin -- who played for Porter at Akron were among the MLS players called up.
