Brazil coach Dunga has said his tournament favourites' confidence is increasing with every match after they eased to a 3-0 victory over Chile.
Man-of-the-match Robinho rounded off a comfortable 3-0 win in Johannesburg's Ellis Park stadium after goals by Juan and Luis Fabiano to secure a quarter-final contest with Holland.
Dunga said: "We know there is always this expectation that Brazil will be the winners but being the favourite does not allow you to win the World Cup.
"Some people doubted that we would perform but as we go along that confidence is growing and growing and we hope to make it to the final."
Robinho, released on loan to Santos by Manchester City last season, insisted he would continue to put individual glory behind his team's achievement.
He added: "I'm very happy with the goal and victory of my team and if I am able to be the best player and top scorer in the World Cup 2010 that will be fine but at the moment I'm concentrating my efforts on the team."
Kaka, on his return from suspension, also showed just why he is so important to Brazil but picked up a third caution of the tournament, from English referee Howard Webb.
Dunga said he will raise the issue with the Real Madrid midfield star.
"It is a problem - I don't want Kaka to be out suspended," he said. "It looks as though the technical players are punished and those who commit fouls aren't always.
"This started happening in the group phase and we are going to talk about this with Kaka. It is a concern for him but we don't want to get bogged down with the issue."
Dunga said the quarter-final would provide Brazil's toughest challenge so far.
"Holland have a great World Cup tradition and they are very similar to the South American teams so we have to be extremely careful," he said.
"We have to be prepared to deal with extremely technical, excellent players. They are a solid team."
Chile coach Marcelo Bielsa refused to be drawn on whether he would stay in his position and admitted Brazil had been too strong.
He said: "The scoreline could have been less high but Brazil's superiority was too much for us, they took advantage of every crack we had in our defence.
"In terms of my own position, for the time being the situation is not right to evaluate what to do next."
