Brazil coach Dunga says the confidence and self-belief they have rediscovered following last year’s World Cup disappointment was critical to their 3-1 victory over France on Thursday.
Since succeeding Luiz Felipe Scolari after their shock semi-final defeat to Germany, Dunga has led the Selecao on a seven-match winning streak - one which Dunga says is owed to their hard work and a new balance to the side.
"These good results are the fruits of work and determination you put into everyday life," the 51-year-old said at his post-match press conference.
"We must continue. Since the World Cup, I have tried to give confidence to the players and to find the right balance."
France opened the scoring at home with Raphael Varane powering a header past Jefferson in the 21st minute but, at the same venue as their World Cup final defeat in 1998, Brazil found a way back into the match.
Oscar levelled the scores before half-time at the Stade de France after a neat one-two with Roberto Firmino. In the second half, Neymar fired the visitors ahead before Luiz Gustavo headed home a corner to put the game beyond les Bleus.
"We played well and we tried to play with speed. We kept our shape well, we were compact,” Dunga said.
"We also had good possession. We committed preventable errors, especially on set-pieces, but once we rectified that, we found the right balance and we got the win."
Dunga, now in his second spell as Brazil coach, went on to reveal that he expects few changes to the side for Sunday’s clash with Chile at Emirates Stadium in London.
"For the Chile game we’ll see which players are fatigued. But we cannot change everyone. We will keep our core."
