Sections of the Sao Paulo crowd booed the football World Cup hosts Brazil during a laboured 1-0 win over Serbia in their last warm-up match.
Coach Luiz Felipe Scolari defended his team's World Cup preparations, after Fred's toepoked winner just saw off the Serbs.
The architect of Brazil's 2002 triumph in Japan reverted to playing good cop and protected his side from the critics in the stands and the media.
Scolari had noted before the game that the five-time world champions often get a rough ride from fans in Brazil's business hub and the Serbia match was no exception at the Morumbi stadium, which will not see World Cup action.
Scolari brushed off the restive reaction of the Sao Paulo crowd after the win, saying his team had got used to being booed by fans, which has happened before.
