The narrow 1-0 victory over South Africa was overshadowed by booing from supporters unhappy with Mano Menezes' team, following on from a disappointing London Olympics final defeat to Mexico.

Ahead of Brazil's double header against Iraq and Japan, Paris Saint-Germain defender Silva appealed to fans to get behind the five-time World Cup winners.

"The less (boos) we hear, the better for us," Silva told Globoesporte.

"Idols and phenomena are born only every 15 years. Not all the time will there be born a Ronaldo, a Romario or a Bebeto."

However, Silva conceded the squad would have to cope if more protests materialised during the friendly matches being staged in Sweden and Poland, as their build-up to hosting the 2014 World Cup continues.

"We need to know how to deal with it all and to try to listen less," he said.
