Brazil coach Dunga was left fuming at referee Stephane Lannoy after he dismissed Kaka towards the end of their 3-1 victory over Ivory Coast in Johannesburg.
The 88th-minute red card for the Real Madrid midfielder came after an off-the-ball incident with Kader Keita. The result of the game already looked to be settled after Luis Fabiano's brace and an Elano strike had helped the South Americans take a 3-1 lead, with the reply coming from Didier Drogba.
"It was a totally unjustified sending-off of Kaka," Dunga said afterwards. "It was a very complicated game, a very physical game I might add."
He added: "There were many fouls committed and all of us, who love football and desire beautiful football, always ask that the beautiful game is controlled.
"We have to know what is good football and what is not. So when the referee allows certain fouls or certain incidents to go unpunished that is not right, as happened here."
And he sarcastically added: "He (Kaka) was fouled and he was punished...he was given a yellow card.
"So it seems that the player that commits the foul is not the one given the yellow card, which means he can do it at will. I must actually congratulate that Ivory Coast player.
"We played much better than Ivory Coast and received more yellow cards than our opponents without really having committed any serious fouls. So we are left a little bit in doubt. What do we really have to do not to receive these yellow cards?"
However, Dunga was pleased with the final outcome and paid tribute to his players.
He added: "All my players played exceptionally well. Luis Fabiano had a great performance. Of course he hadn't scored in the last five matches, so we are really pleased for him."
