Dunga insisted his side did all they could to win the match...
"We want to win always,” Dunga, whose side strolled to a goalless draw today, told Brazilian TV.
“We are not happy with the result. We tried to attack them until the end. The opponent was defending.”
The draw was enough to send both sides through to the second round and they left the field to a chorus of boos in Durban.
"When teams play Brazil, they try a different kind of strategy. It's normal,” he continued.
“As the Brazilian coach, I would choose Lucio [as man of the match] as he intercepted every ball. The people that have chosen Cristiano Ronaldo have obviously seen some good things [from him]. I didn't see a lot, apart from his obvious technical quality.
"As for mistaken passes, it's tough when you face a team that just stay back,” he continued. “But I thought we could have played more on the wings. We played too narrow.
“Switzerland had a strategy against Spain, but it does not mean that they play like this all the time. Spain plays a more offensive style. But you have to analyse it match by match and play it accordingly.”
Dunga went on to take another jab at Portugal, blaming their overly aggressive approach for the poor quality of the match.
"Brazil was already qualified, so I don't know why the game was nervous,” he said.
“You have to ask [Portugal coach Carlos] Queiroz that. You have to only look to the number of yellow cards to see which team was more violent.”
The draw means Brazil win Group G and will face the runner-up of Group H in the next round, either Spain, Chile, or Switzerland.
