Neymar is very happy with the way returning coach Dunga is guiding Brazil and hopes to stick to the winning path at the expense of Ecuador in New Jersey.
After securing a 1-0 triumph over Colombia thanks to a solitary Neymar goal, the Selecao continue on their road to redemption after enduring a seriously embarrassing end to their World Cup campaign.
Brazil will have to cope without David Luiz (knee) and Maicon, who has reportedly been excluded from the squad due to indiscipline.
The official line from national team coordinator Gilmar Rinaldi is that there has been "an internal problem" with the Roma full-back.
Neymar told reporters that Dunga, who replaced Luiz Felipe Scolari in July, has "determination and desire".
The Barcelona striker said: "Our coach has proved to us that he is serious. Neither of us wants to lose any game."
Meanwhile, Dunga said the victory over Colombia has lifted his team's self-esteem following the cataclysmic fall-out of their 7-1 semi-final defeat to Germany in Belo Horizonte.
"We were all torn up, but managed to produce an answer, a reply," said the Brazil boss.
"Victories are always good for silencing your critics."
Ecuador head into the match after notching a 4-0 win over Bolivia in Fort Lauderdale and Junior Sornoza, who marked his international debut with a goal on Saturday, is hoping to emulate that performance against Brazil.
The Independiente del Valle forward told local station Radio La Red: "I think we can do it because we have fast players.
"We hope we can do well against Brazil, although it will be a very tough match."
"We are aware of their strengths and we must be intelligent.
"We are happy with the way we've been doing our jobs so far. The group is united and that is very important."
