Liverpool's Philippe Coutinho hit a hat-trick as Brazil coasted to a 7-1 Copa America Group B victory over Haiti in Orlando.
Renato Augusto hit a brace for Dunga's side, while Gabriel and Lucas Lima also netted for the rampant Brazilians with Haiti's solitary reply coming from James Marcelin.
The Liverpool midfielder netted his first on 14 minutes, picking the ball up on the left and cut inside onto his right foot and sent a superb effort past Placide.
And it was Coutinho who doubled Brazil's advantage after 29 minutes with the simplest of tap-ins. Dani Alves found Jonas, who played in an unmarked Coutinho in front of an empty net.
Coutinho got his hat-trick two minutes into stoppage time, rifling home with the last kick of the game to become the first Brazilian to hit a Copa America hat-trick since Robinho in 2007.
Brazil coach Dunga hailed Coutinho for delivering his Liverpool club form in his country's colours, saying: "We have talked quite a lot to him about being the 'Liverpool Coutinho' - to take the initiative, be a leading part of the team, all within his own style.
"He is really taking advantage of the opportunities he has been given. After his first goal you could see him gain confidence and a player with confidence is always going to be better."
