Brazil warmed up for their Copa America campaign with a 1-0 victory over Honduras thanks to a first-half strike from Roberto Firmino.
It was a sluggish start from the hosts in Porto Alegre, but they improved as the first half progressed and created the first clear chance when Philippe Coutinho played through Firmino, who could only fire an effort straight at Noel Valladares.
Dunga's side continued to pile on the pressure and they came even closer to breaking the deadlock when the lively Willian rattled the post from a tight angle.
The opener finally arrived when Filipe Luis sprinted into space before picking the perfect pass to allow Firmino to slot past a helpless Valladares.
Honduras asked more questions of the home defence early in the second half when Andy Najar fired wide from distance, before Anthony Lozano failed to hit the target from close range a few moments later.
Neymar, who was sent on as a half-time substitute, forced Valladares into a fine save just after the hour mark, and the Honduras goalkeeper was alert once again to keep out a Miranda effort.
The Barcelona forward almost added a second late on when his free kick drifted just wide of the target, but Brazil were forced to settle for one goal before they travel to Chile for the start of the tournament.
