Giovani dos Santos
The playmaker was one of the breakout stars of the 2010 World Cup and backed that up as one of Mexico's best players in the 2011 Gold Cup. Born in 1989, Dos Santos is still young enough that he didn't cost Mexico one of its three over-age selections.

The creative midfielder has been called the female Zinedine Zidane (at least partially due to her Algerian heritage). At 25, she still has plenty of time to live up to that comparison after being one of 10 nominees for the 2011 FIFA Ballon d'Or.

Schelin will be key if Sweden is to break up a potential U.S.-Japan rematch. The Swedes' best striker scored twice in the 2011 World Cup, where Sweden was the only team to beat the U.S. in regulation.

Will this be the final Olympics for Wambach? The 32-year-old striker scored the game-winning goal in the final of the 2004 Olympics and then missed the 2008 Olympics with a broken leg. She'll look to lead America to its fourth gold medal (and third straight) in five women's Olympic tournaments.
