Brazil goalkeeper Julio Cesar has warned his team-mates to pay attention to long-range shots in order to avoid surprises in the World Cup qualifying trip to Bolivia on Sunday.

Brazil have already booked their place in next year's finals in South Africa and are now fighting to top the standings after the final two games this week.

Dunga's team will play at 3,600metres above sea level in La Paz and Cesar is sure the hosts will attack by shooting from outside the box.

"At altitude Bolivia shoot a lot. We must be focused and our defensive system should be ready to get rebounds," the Inter Milan goalkeeper said.

Dunga revealed he has already decided most of the players who will compete in South Africa next year, but does not want them to feel overconfident.

"It is obvious that the ones who played the Copa America (in 2007) and the Confederations Cup (this year), the ones who played Argentina, Paraguay, Uruguay and Venezuela have a little advantage.

"But they don't have their places secure."

Brazil will be without injured defenders Lucio and Juan, while Bolivia's new goal is simply avoiding finishing bottom of the standings.

To achieve that goal, coach Erwin Sanchez is preparing a very defensive team to play at the Estadio Hernando Siles.

He said: "The important thing is to keep the players' will as high as if it was the first match. They know very well that they should be professional until the end.

"I hope the result will be good for us. Brazil are a great team with great players and we hope we can hold their power."
