Two upstart squads meet in Mendoza, Argentina, when Venezuela faces Paraguay in the Copa America semifinals.

Paraguay may have pulled off the upset of the tournament when they held off South American giants Brazil, in the quarterfinals. Riding the momentum, Paraguay goes into the semifinals match with one of best defenses on the continent.

Shutting out Brazil for 120 minutes in no easy feat. Paraguay have also shown they have a decent attack in forwards Roque Santa Cruz, and Nelson Haedo Valdes.

Not that Paraguay are delusional about their status in Copa America.

We're not favorites, said Paraguay head coach Gerardo Martino. We are realists and a team who in a period of four and a half years have lost to Qatar, South Africa and Honduras cannot be considered favorites.

As much as Paraguay appeared to be the underdog in this tournament, Venezuela is probably more of a surprise to be in the semifinals.

Venezuela has a solid roster, though no superstars to speak of. In midfield, Bundesliga regulars Tomas Rincon and Juan Arango have proven to be a solid contributors.

Venezuela will need to prove they have a real attack with Estudiantes' goalkeeper Justo Villar minding the net. The 34-year-old has proven to be among the best goalkeepers in the tournament.

The winner faces Uruguay, a squad that boasts world-class talent.
