Brazil boss Dunga was unhappy with the decision made by French referee Stephane Lannoy to send Kaka off in their 3-1 win over Ivory Coast.
The Real Madrid star was given his marching orders in the 88th minute for a off-the-ball incident involving Kaider Keita, infuriating Dunga who was furious at not just that decision, but for plenty others throughout the match.
"It was a totally unjustified sending-off of Kaka," Dunga said. "It was a very complicated game, a very physical game I might add.
"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 today.
"He (Kaka) was fouled and he was punished...he was given a yellow card," Dunga added mockingly.
"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?"
