Brazil coach Dunga was jeered by the fans after the five-time world champions drew at home to Argentina.
The result meant they climbed back into the fourth and final qualifying place in the South American qualifying group for the 2010 World Cup.
But Argentina were the better side, Julio Cruz hitting the bar and Lionel Messi twice going close in injury time.
Brazil's Manchester United midfielder Anderson had to leave the field after twisting his knee.
Brazil are in the middle of a miserable run of form, having lost to Venezuela for the first time ever earlier this month in a friendly and followed that up with a 2-0 defeat by Paraguay, who lead the South American standings, on Sunday.
However, keeper Cesar was satisfied with the result against Argentina.
"We played a great team with a lot of experience," he said. "We played completely different than we did against Paraguay - we played a great defensive game but just couldn't get a goal."
The crowd lost patience with Dunga in the second half, chanting "Goodbye Dunga" at one point and "Donkey, donkey" when he replaced Adriano with Luis Fabiano.
Brazil: Julio Cesar, Maicon, Juan, Lucio, Juan, Gilberto, Gilberto Silva, Mineiro, Anderson (Diego, 33; Daniel Alves, 78); Julio Baptista, Robinho, Adriano (Luis Fabiano, 74).
Argentina: Roberto Abbondanzieri, Fabricio Coloccini, Nicolas Burdisso, Gabriel Heinze, Javier Zanetti, Javier Mascherano, Fernando Gago, Jonas Gutierrez, Juan Roman Riquelme (Jonathan Battaglia, 83), Lionel Messi (Rodrigo Palacio, 89), Julio Cruz (Sergio Aguero, 70).
