Johannesburg: Brazil, a team once associated with style and panache, were praised by coach Dunga for their efficiency after beating North Korea 2-1 in their opening World Cup game on Tuesday.
The Brazilians produced a shocking first-half display but did just enough after halftime to take three points in their first game of a campaign in which they will attempt to win an unprecedented sixth World Cup.
"It`s all about efficiency," said Dunga, a former hard-tackling midfielder who has built the team in his own image and included only four recognised forwards in the 23-man squad.
"Everyone has to be efficient, in attack and defence. Without that you don`t get anywhere."
Dunga`s team have often managed to win matches in which they have been outplayed thanks to isolated moments of individual brilliance, and depend heavily on counter-attacks and set-pieces to score.
"When you meet a team which attacks you, you create spaces," said Dunga, sounding as if he was about to blame the North Koreans for being spoilsports.
"When they are completely closed, it`s more difficult to play on the counter-attack and you have to keep plugging away."
He admitted Brazil struggled in the first half.
"At the start we were passing the ball around from side to side. "I`m satisfied with the win but I want more, I want us to score more goals."
