Brazil take on Japan in a friendly at Singapore's National Stadium on Tuesday.
The Selecao have been in good touch since the appointment of new boss Dunga, recording successive wins in their last three fixtures against Colombia, Ecuador and Argentina.
The 2014 World Cup in their own backyard proved to be a disaster for Brazil as they succumbed to heavy defeats against Germany (7-1) and Holland (3-0), in the semifinals and the third place match respectively.
Brazil head coach Luiz Felipe Scolari was sacked after the World Cup and was replaced by Dunga, who has been able to pick up the pieces and get some positive results. The victory against Argentina was especially impressive, considereing they fielded a relatively weak squad, compared to their South American rivals.
However, Dunga insists that all the good work in the last couple of months will be wasted if they slip up against Japan.
"The Selecao has to work beyond football quality and results. If we lose focus in the Japan game, all we've been doing so far will be lost and criticism will come up. They will say the national team is not the one it used to be any more," Dunga told ESPN.
The 50-year-old insists that his side will be looking to put up a good show against Japan, despite admitting that the tricky playing surface in Singapore will somewhat hamper his side's playing style.
"The quality of Brazilian players means were are always expected to put on a good show, but we need a good pitch to play speed and with intensity. The intention, every time we play, is to produce a good show," Dunga told Goal.
Meanwhile, Japan will also be hoping to continue their winning ways, following their recent 1-0 win against Jamaica in a friendly.
Manager Javier Aguirre, who was appointed as Alberto Zaccheroni's successor following the Italian's resignation after the 2014 World Cup, did not have the brightest start to his new career as his first two games in charge of the Samurai Blue ended in a defeat and a draw against Uruguay (2-0) and Venezuela (2-2) respectively.
Although Aguirre was able to guide Japan to a 1-0 win against Jamaica, they are not expected to do so against Brazil, considering the Selecao's recent run of form.
However, despite acknowledging the difficult of the task ahead, Aguirre feels that Japan will do well against Brazil if they play the same way they played against Jamaica.
"I'm as relaxed as I always am," Aguirre told Kyodo News. "If we play the way we did [against Jamaica] we might have a chance against Brazil. We had 20 shots against Jamaica. Against Brazil we might have one - and we'll need to take that."
