A first-half goal from Chelsea’s Willian was enough to give Brazil victory over Ecuador in Tuesday’s international friendly in New Jersey.
It was a second successive 1-0 win for new coach Dunga, following last week’s friendly with Colombia in Miami.
Chelsea’s Oscar, Ramires and Filipe Luis were also in the Brazil line-up.
The winner came from a free-kick on the half-hour as Oscar found Neymar, who lifted over the defence for Willian to score with the outside of his foot.
Ecuador almost equalised six minutes later but Enner Valencia’s right-foot shot hit the base of the post after beating goalkeeper Jefferson.
The West Ham striker also saw a looping header cleared off the line by Luis 16 minutes into the second half as Ecuador enjoyed their best spell of the game.
Brazil, who also included Liverpool’s Philippe Coutinho and Manchester City’s Fernandinho among their substitutes, had their best chance of the second half in the 47th minute but Neymar missed an open goal from four yards out with the goalkeeper on the ground.
The next match for Dunga’s team will be against Argentina in Beijing on 11 October, with his first competitive fixtures in next year’s Copa America in Chile.
