Brazil coach Dunga was pleased with the improvement in his side's performance as they saw off Ivory Coast 3-1 in Johannesburg to qualify from Group G with a game to spare.
Goals from Luis Fabiano (2) and Elano put the samba stars in an unassailable position before Didier Drogba's late consolation goal, but the gloss was taken from the win when Kaka was dismissed late on after a clash with Kader Keita.
Dunga commented to journalists afterwards that he was delighted that the side looked superior to their display versus the North Koreans."
It was a game where we had to pay attention because it was a fast team who was physical," he said.
"Sometimes they criticise me because Brazil has difficulties with teams that stay back. I ask, what team does not have those difficulties?
"The first game is always difficult to everyone. We saw that the second round was better. Today we played against a team that is strong physically. I though that we worked with the ball better and were more patient on build-ups".
Laughing it off | Kaka is in disbelief as he is dismissed in controversial fashion
Dunga also addressed Kaka's dismissal, after being noticeably animated when the referee showed the red card to his playmaker, and insisted it was not a just decision.
He added: "We will think who will replace Kaka in the next days. The red card was not fair. His first yellow card, he suffered the foul.
"Since we got here, we talked to the players and warned them that we have to finish with eleven. I think we have to play hard, but play football."
Brazil round off Group H with a match versus Portugal on Friday, with qualification already ensured.
