Brazil beat Ecuador 1-0 in an international friendly in New Jersey, United States, late Tuesday with a first-half goal from Willian enough to give coach Dunga his second successive victory.
The win came four days after Brazil beat Colombia and the win over a sprightly Ecuador side delighted the new manager.
“There weren’t any negative points,” he told reporters.
“You have to take positives from the negatives. You learn, you evolve. So for me it was all positive.”
Brazil’s winner came on the half-hour from a well-rehearsed free-kick.
Oscar hit a short pass to Neymar who lifted a curled pass over the defence to Willian and he slipped it into the net with the outside of his right foot.
Ecuador almost equalised six minutes later but Enner Valencia’s right foot shot hit the base of the upright after beating goalkeeper Jefferson.
The West Ham United striker also had a looping header cleared off the line by Filipe Luis 16 minutes into the second half as Ecuador enjoyed their best spell of the game.
Brazil’s best chance fell to Neymar but the striker missed an open goal from four yards out with the keeper on the ground.
Brazil’s next match will be against Argentina in Beijing on Oct.11.
