Brazil will look to heed the lessons of the 2011 Copa America when they meet Paraguay in Saturday's quarter-final in Concepcion.
Four years have passed since the two teams locked horns at the same stage when the South American showpiece was contested in Argentina.
Brazil have the chance to avenge that defeat, although Dunga's men have yet to hit top form despite topping Group C.
Dunga will have to make do without Barcelona superstar Neymar, who will sit out the rest of the tournament having been banned for an attempted headbutt on Colombia's Jeison Murillo.
In the absence of the talismanic skipper, Robinho was drafted back into the side and is expected to keep his spot after impressing against Venezuela, while the likes of Willian and Liverpool-bound forward Roberto Firmino also shone in Neymar's absence.
"Brazil without Neymar is different, but we know that they still have great players," he told Tigo Sports. "But we are calm, and working to get the result.
"Against Uruguay, we knew that we were going to have a match with a lot of contact. Play was stopped many times because Uruguay is known for that. But that may be the exception. We will have a great game against Brazil."
