Ten-man Brazil and Chile drew 2-2 in a friendly in Belo Horizonte, with a chorus of boos ringing around the Mineirao stadium following the final whistle.
The visitors took an early lead as midfielder Cesar Cortes' header was saved by Diego Cavalieri and Marc Gonzalez converted the rebound.
Brazil almost levelled in the 15th minute, but Jadson's long-range shot hit the crossbar, with Ronaldinho's rebound effort saved by Johnny Herrera, but they did get the equaliser when Rever headed home Neymar's corner.
During the second half, Alexandre Pato assisted Neymar, who only had to push the ball into the goal to fire Brazil ahead, but Eduardo Vargas fired his side level in the 64th minute with a superb long-range shot.
In injury time, Braulio Leal fouled Fernando Meneses and was sent off.
The crowd became more restless as the home side were unable to put away their opponents as the second half wore on, and jeers could be heard following the issue of a late red card.
"One day you're booed, the next you're praised, football's like that," said striker Neymar.
Pato added: "It wasn't what we expected. We have to keep working.''

Captain Ronaldinho was also philosophical about his team's performance after the match, explaining that the domestic-based squad lacked cohesion in the early exchanges.
"It's difficult with a team that only trained once. We tried but everyone knew it was going to be tough," he said.
2014 World Cup hosts Brazil have won one, drawn three and lost one of their five games under coach Luiz Felipe Scolari, who is enjoying his second spell in charge of the Selecao. His next job will be to select his squad for this summer's Confederations Cup.
