Kaka was dismissed after an off the ball altercation with Abdelkader Keita earned him a second yellow card.
Dunga stated: “It was a totally unjustified dismissal of Kaka, he was fouled and yet he was punished. The player who commits the foul escapes the yellow card, I have to congratulate him for that.
“We are left a bit in doubt, what do we have to do in order not to receive these yellow cards?”
