Brazil played a scoreless draw with Venezuela in their first Copa America match, and their second match on Saturday in Cordoba promises to be more difficult.

One of the favorites to win the South American tournament, Brazil will face a tough Paraguay squad that plays very good defense.

Six out of seven opponents have failed to score against Paraguay, and Ecuador couldn't score in the first game.

After not scoring against Venezuela, and facing a stingy defense in Paraguay, Brazil will need a big game from forwards Neymar, Robinho, and Alexandre Pato.

The bulk of the responsibility may fall on the shoulders of the Brazilian midfield. They will need to be more creative in getting their talented trio of forwards the ball in the right spots, while also containing Paraguay's counter attack.

Paraguay is led by veteran central defender Paulo da Silva, who plays in La Liga for Real Zaragoza, and 23-year-old left wing Marcelo Estigarribia who plays in the Argentine league for Newell's Old Boys while on load from French club Le Mans.

Paraguay's best scoring option is Lucas Barrios, a striker for Bundesliga club Borussia Dortmund. He has scored 44 goals in 67 appearaces for the German club.

Barrios faces perhaps the best defense in the world in Dani Alves, Lucio, Andre Santos, and Thiago Silva, and a bench that has Maicon and David Luiz, a star in the making with Chelsea. Julio Cesar, who stars for Inter Milan, is among the best goalkeepers in the world.

On Wednesday, Brazil will face Ecuador, while Paraguay plays Venezuela.
