Brazil was beaten 2-0 by Chile in its opening 2018 FIFA World Cup qualifier but Carlos Dunga does not believe the panic button should be hit just yet.
Second-half goals from Eduardo Vargas and Alexis Sanchez secured maximum points for the Copa America winner in the opening round of qualifying games for the finals in Russia.
Dunga, however, insists the game was evenly balanced and has rejected suggestions for an overhaul of the team ahead of the home fixture with Venezuela next Thursday (AEDT).
"It's very difficult for a coach to talk about changes after a 2-0 defeat. It's not always necessary to change everything after a loss," he said.
"It was an equal game in the first half, we had some good chances before Chile's first goal. Football is like that.
"We had four or five counterattacks that could have been killers, but we didn't make the right choices.
"Nobody likes to lose, but the match was very even. Everyone knows Chile are a difficult team to play against. We knew we would face pressure.
"The home games will be crucial. We always have to get three points at home."
