The five-time World Cup winners lost 2-0 against Mexico in their Group B opener on Wednesday night and are anxiously aware another defeat could spell the end of their campaign.

But Dunga, while confident, is not taking anything for granted against a side his men beat 4-0 in a friendly three months ago.

He said: "We have to respect Chile. We won the last friendly, but we had an early penalty goal that made things easier for us.

"Brazil are heading in the right direction. We only have to correct some details."

Real Madrid striker Robinho added: "When a team plays against Brazil, they want to beat us.

"If we want to be champions, we have to beat Chile, but with humility."
