Neymar was on target in Thursday's 3-1 win over France, moving his overall tally to 43 in 61 internationals.
Pele, widely regarded as the finest player to grace the game on the back of World Cup wins in 1958, 1962 and 1970, registered 77 goals in the famous Brazil jersey.
Dunga succeeded Luiz Felipe Scolari on the back of that humbling reverse and has overseen seven consecutive victories, with Neymar scoring eight of the team's 17 goals.
In 1994, Dunga lifted the fourth of Brazil's five World Cups as captain and he insists Neymar will ultimately be judged on whether he can help add to this rich history and not on any personal landmarks.
"Neymar is doing very well and will only grow," he told a press conference ahead of Sunday's friendly meeting with Chile at Arsenal's Emirates Stadium.
"In regard to [matching Pele's] goals I don't think that will be a problem. But the record we really want him to get is Pele's number of World Cup wins."
"I think not,” he said. "I think to be the new king, the new Pele, is impossible because my mother and my father closed the machine.
"I think he's a good player, an excellent young player and he's going to be a big star, no doubt."
