Portugal coach Carlos Queiroz issued a stark warning that his team will be "more ambitious" over the course of the World Cup after their 7-0 hammering of North Korea.
After labouring in their opening Group G stalemate with the Ivory Coast, Portugal delivered a ruthless display against North Korea. They now head into their clash with Brazil full of confidence after six goals in the second half made a serious statement to their rivals.
"It is a great day for Portugal and Portuguese football, to score seven goals," said Queiroz. "We have to be more ambitious for the next phase."
He added: "It's a feeling of great satisfaction for our players in the way they played, the attitude and perseverance with beautiful football and beautiful goals.
"I'd like to register my respect for the North Korea team. They leave with their heads held very high but sometimes we have to face these results."
Raul Meireles scored in the first half before Simao Sabrosa, Hugo Almeida and Tiago hit one apiece within seven second-half minutes. Liedson and Cristiano Ronaldo got in on the act before Tiago grabbed his second in the dying minutes.
Portugal came into the match hoping to boost their goal difference with the Ivory Coast, their main rivals to join Brazil in the next round, still to play a North Korea who were excellent in their 2-1 defeat by Dunga's side in the first game.
North Korea coach Kim Jong-hun was quick to shoulder the blame. "Tactically speaking we fell apart and we didn't block their attacks," he said.
"As a coach it was my fault for not playing the right strategy and that is why we conceded a lot of goals.
"Portugal became more aggressive as the game continued and it was our desire and wish to equalise that led to the collapse. The attack and defence was not balanced well."
