The Barcelona forward netted four goals as Brazil continued their dominant start since the return of coach Dunga, after Scolari was sacked for Brazil dismal end to the World Cup in July.
Neymar opened the scoring in the first half, and capped off a brilliant performance with a second-half hatrick at the Singapore Stadium, in what was the first four-goal haul by a Brazilian since Romario’s in 2000.
Dunga, who has now helped the Selecão to their fourth win in as many matches since returning to the helm, has praised the 22-year-old’s passion and enthusiasm for the game.
“When we started with the Selecão, we said that we would all contribute to the growth of Neymar," he said after the win in Singapore.
"He assumed the matter of the captaincy well. Neymar enjoys playing football and is not satisfied with just a little. If he was playing with friends he would have the same enthusiasm as he does playing for the Selecão.
"With the creativity that he has, he can do something different every game," said Dunga.
