Omar Gonzalez isn't the only young American impressing at a young age.

Ives Galarcep presents some other U.S. national team prospects working their way up the pipeline.

One of the most impressive rookies in MLS, Ream has become one of the most important keys to the New York Red Bulls turnaround. A 22-year-old central defender with impressive passing skills and intelligence, Ream has already caught the eye of European clubs.
 

A long-time standout at Wake Forest, Opara figured to adapt well to MLS because of his freakish athleticism and Opara stepped right in and made an impact for the San Jose Earthquakes. He has shown an ability to score goals, and is one of the most dominant players in MLS in the air. A broken foot has sidelined him, but the 21-year-old is still one of the best young American prospects around.
 

Lichaj skipped a college career to give Europe a try and the decision is starting to pay dividends. The Aston Villa fullback spent last season on loans with lower division clubs to gain experience, and now he stands a good chance of an increased role with Villa. Just 21, Lichaj just made his first-team debut for Aston Villa in a recent Europa League match, and recently signed a new three-year deal with the English club.

Arguably the second most impressive rookie defender in MLS in 2009, Alston drew raves as one of the best young fullbacks in MLS. The New England right back combines speed, athleticism and tenacity with good skill, leading one top MLS head coach to call him the best right back in the league. He’s just 22 and could be the next Revs player to make the jump to Europe.

Agbossoumonde is still very young, and has yet to make his professional debut, but his skill set has scouts and fans already buzzing about his bright future. The 18-year-old central defender already boasts impressive size (6-foot-2), but he also flashed some goal-scoring ability in leading the U.S. Under-20 national team to its Milk Cup championship.
