Brazilian president Dilma Rousseff has urged the country to "get up, dust yourself off and bounce back" after its humiliating 7-1 defeat to a rampant Germany in last night's World Cup semi-final.
Rousseff said on Twitter that "like all Brazilians, I'm very, very sad about the defeat."
She added: "I'm immensely sorry for all of us, our fans and players. But let's not let ourselves give up. Brazil, get up, dust yourself off and bounce back."
Brazilian president Dilma Rousseff has defended the decision to host the World Cup, which has been heavily criticised in the country, and said the South American nation was ready for football's premier competition.
Ms Rousseff defended the cost of hosting the competition, vowed to punish corruption and urged compatriots to give visiting fans a warm welcome, in a television address.
The World Cup is set to kick-off tomorrow, with the host nation opening the tournament with their match against Croatia, and the president claimed "the pessimists" had been defeated by the determination of the Brazilian people.
She also rejected criticism that the country had overspent on the World Cup - which is set to cost close to £6.6 billion - saying the tournament would leave a lasting legacy.
Brasil's president Dilma Roussef has called an emergency meeting of cabinet ministers to discuss how to respond to the groundswell in protests across the country, according to local newspaper O Globo.
The newspaper reports that Roussef is considering making a statement directly to the protesters via television and radio.
She may also convene the Council of State - a body of the country's top leaders called in cases of national emergency - it is reported.
