The USMNT gets set for their toughest test yet as they get ready to face off against Lionel Messi and Argentina in the semis of the Copa America.

"There's no reason at all why we can't win Copa America," USMNT manager Jurgen Klinsmann said. "We travelled the world the last few years to very difficult friendly games all over Europe and in Mexico and we came away with wins.

"We surprised a lot of people -- no one gave us a chance to get out of the group in Brazil [at the World Cup]. We left Portugal behind, we left Ghana behind.

Messi will be the focal point for the U.S. as they look to stop the best player on the planet to reach their first ever Copa America championship game. Messi has been the most prolific player in the Copa America tournament thus far. In the team's second game against Panama, Messi scored three goals off the bench in his first 19 minutes in the game.

The U.S. will be without three key players on Tuesday night as Bobby Wood, Jermaine Jones, and Alejandro Bedoya are suspended due to yellow card accumulation. Wood leaves a big hole in the U.S. attack that will likely have to be filled by Graham Zusi, who the U.S. has gone to when substituting for either Wood or Dempsey.

The Game is scheduled for 9:00 p.m. on FS1.

"Dream big -- why not? This is about two more games," Klinsmann said.
