Brazil coach Dunga admitted that his side struggled to cope with Edinson Cavani and Luis Suarez as Uruguay came back from 2-0 down to salvage a 2-2 draw in their World Cup qualifier on Friday.
Douglas Costa and Renato Augusto had put Brazil ahead but Dunga's men let their foot off the gas in the second period and Cavani and Suarez struck back to save a point.
"That first half the team got off to a good start, rolling the ball and making most of the space," Dunga said. "In the second half we were more static, without the same movement. Uruguay took advantage of it.
"In one half Brazil played, in the other it was Uruguay. To play against an attacker like Cavani, like Suarez is not easy. It's never easy to play against Uruguay."
Neymar will miss Brazil's next qualifier away to Paraguay after picking up a yellow card and Dunga said the winger was on the end of some tough decisions.
"As for the foul he gave away to get the yellow card, there should have been yellows for the fouls he received," Dunga added. "The foul was not bad enough to receive a yellow. But it's Neymar, and the referees will always be rigid with him."
