Dunga has sought to ease worries that Brazil will continue its poor form in the enticing 2010 World Cup qualifying encounter with Argentina on Wednesday and promised that things will improve.
After seeing his side lose to Paraguay last weekend, and having been beaten by Venezuela in Boston earlier this month, critics slammed the coach and the players for their performance.
Now though, Dunga believes that his team is ready to show what it can really do and put in a strong performance against the Albiceleste in Belo Horizonte's Estadio Mineirão.
"These players have already proved their temperament, their quality, their personality," he was quoted by Football 365. "They are used to dealing with criticism. They have already brought joy to supporters and they want to do it again. We didn't play well against Paraguay, but we'll do much better against Argentina."
Dunga is refusing to be cajoled into making numerous changes to his team and is confident that those that played on Sunday will step up a level.
"Sometimes, changing attitude is better than changing starters," he continued. "I will talk to the players, analyze, but this isn't a match that will change the way we play. We'll try to recover our form against Argentina and try to play the same football we used to play."
Adriano told reporters that he is ready to play again if required after coming on in the second half of the game against Paraguay and hopes he is in the coach's plans.
"I am ready to play, waiting for any opportunity Dunga can give me," he explained. "I obviously want to play. He knows what to do and what he will do will be good. I am truly happy."
