Left back has a been a traditional weakness for the USMNT. It has been a revolving door with nobody able to get a firm grip on the position. Could the next generation of left backs provide more stability? It is possible. Here are the top five left back prospects in the American player pool:

1. Anthony Wallace,  20, FC Dallas

He has good size to go along with blazing speed. He started four games in the 2007 U-20 World Cup. He has  been getting consistent playing time with FC Dallas this season, which should speed up his development. He will be playing in the U-20 World Cup again later this year.

2. Tim Ward, 22, Chicago Fire

He is a great example of not giving up on a player too soon. He had a poor performance in the opening match of the U-20 World Cup and has bounced around since then. He is with his fourth MLS club, but has finally emerged as a solid prospect.

3. Matt Besler, 22, Kansas City Wizards

He has nailed down a starting position with the Wizards during his rookie campaign. He plays smart and reads the game well. He does not have a flashy resume of past youth national team experience but has made up for it with hard work.

4. Kevin Alston, 21, New England Revolution

He is starting due to some injuries, but has looked solid in his eight starts. He has great speed and can get forward into the attack easily. He can play on both the right and left side.

5. Blake Wagner, 21, FC Dallas

He has been playing professional soccer for three full seasons. The Generation Adidas product made 23 starts last season, making him to the most experienced player on the list. He can also play in the midfield.
