"In this World Cup we are seeing that every team puts a lot of players behind the ball when the other team has possession and Ivory Coast also showed that against Portugal. We have to be very efficient because we might not get many chances to score," Dunga was quoted as saying in a press conference.
"Ivory Coast are a well organised team under new coach Sven-Goran Eriksson. They will probably attack more than North Korea. They have a lot of quality in their squad. We will have to pay attention to the aerial game and I expect a physical game.
"It's difficult to be the coach of a national team because of the pressure. The coach has to be well balanced and has to understand that the focal point is the team. Everything else is less important.
"Brazil have quality players who can decide a game in one moment. The most important thing is that the group is focused on winning the tournament. Everyone who has seen the training sessions knows how committed the lads are."
Brazil have a 22 per cent chance of lifting the tophy in July, according to Castrol Football's 2010 FIFA World Cup Success Predictor.
