American players can be found playing on teams across Scandinavia and in countries like Belgium and Scotland, but many of these players have not been given the opportunities that German- and Mexican-based players have received.
While the Bundesliga is of a higher quality than the other aforementioned leagues, playing time, team quality and the struggles of American players from the Mexican Primera raise questions as to why other foreign-based players haven't been given a chance.
Alejandro Bedoya, Sacha Kljestan, Clarence Goodson and especially Oguchi Onyewu all made great strides playing in these lesser-known European leagues, and yet current players from such teams have been given few call-ups.
So how important is it to go overseas?
Even though Mikkel Diskerud has earned consistent playing time at Stabaek in Norway, his reward was a call-up to the Under-23 national team even though he has already earned a senior-team cap under Bob Bradley.
Considering Mixx's technical abilities, he appears a shoo-in for Klinsmann's style of play, but he has been frozen out.
Josh Gatt, Bedoya, Kljestan and Chris Rolfe are other high-profile, high-potential players plying their trade in lesser-known European leagues that could have something to add to the national team.
Klinsmann has gone on record stressing the importance of the foreign league experience for American players, but would it be better for some players to stay in the MLS or look to Mexico before playing in Scandinavia?
Outside of the major European leagues, it seems that Klinsmann has an eye for North American-based players.
Klinsmann will have to be clearer (and he may be behind closed doors) on what he perceives as a strong foreign-based move for players, and what significance playing in a lesser-known European league actually holds for a player's international career.
This is especially important as many American players look to Scandinavia as a doorway to the more prestigious European leagues, as well as fulfilling their national team manager's requirement of moving overseas, but if such a move stalls a player's international career, is such a move worth it?
Klinsmann will have to sort this out.
