Brazil will want to put away a disappointing opening performance in the Copa America Centenario and get that first win under their belt, when they play Haiti in Orlando on Wednesday.
Dunga's men looked toothless in front of goal without their superstar Neymar, with Ecuador feeling a little aggrieved in the end, as they came away with a goalless draw. Brazil were lucky to have a goal chalked off, when replays suggested it really should have stood.
The worrying thing about that Brazil performance against Ecuador was that it was not unexpected. Coming into the match, Ecuador would have been the one expected to play the more enterprising football, while Dunga's side would have been tipped to struggle to fashion a substantial chances in front of goal. So it proved to be as well for Brazil, despite holding most of the possession against Ecuador.
Brazil cannot afford to be so profligate in front of goal against Haiti, a team they will be expected to beat comfortably.
"Our game had some positive things and also some other things we can improve on," Brazil coach Dunga was quoted as saying by Goal. "Even though we could not train much together due to people finishing the end of their seasons, we are doing a good job.
"We will only continue to grow throughout the tournament. (Against Haiti) we must win by any means, and we cannot get another bad result."
Haiti are coming off a 1-0 loss to Peru, with Paolo Guerrero consigning them to a narrow defeat. Considering Brazil are not exactly looking like the most threatening team at the moment, Haiti might just consider an upset possible.
For Brazil to avoid that from happening, their big players need to step up. The likes of Willian, Philippe Coutinho, Hulk, if given an opportunity, and Lucas Moura need to show their attacking skills and put the game to bed in the first half.
"There were many good things that came from the game versus Ecuador," Brazil defender Marquinhos was quoted as saying by the Daily Mail. "We implemented a lot of the tactics there were given to us by Dunga.
"We need to have our feet on the ground against Haiti. We need to respect our opponent and know that nothing is given to us just because we are the Selecao. We need to perform and we need to earn all the points we get.
"There are no such things as an easy game in the Copa America. We are focused on getting a positive result versus a Haiti team that played very well versus Peru."
