Dunga has made wholesale changes to the Brazil squad with just 10 players retained from the 23 who were involved at the World Cup.
The 50-year-old was re-appointed to the role last month after Luiz Felipe Scolari resigned following Brazil’s devastating 7-1 semi-final defeat to Germany on home soil.
Brazil face Colombia – who they beat in the quarter-final of the World Cup – in Miami on September 5 and then Ecuador on September 9 in New Jersey.
Dunga, who managed Brazil between 2006 and 2010, has called up 22 players for the friendly matches.
Among those not selected is Barcelona’s Dani Alves. The 31-year-old started the World Cup as Brazil’s first-choice right-back, but was dropped in favour of Maicon as the tournament progressed.
Alves’s omission is noteworthy, not least because unlike David Luiz say, who retains his place, he was not involved in the defensive debacle against Germany.
Among those promoted to the squad are Liverpool’s Philippe Coutinho, whose form at the tail end of last season prompted calls for him to be included in Scolari’s World Cup squad.
Paris Saint-Germain centre-back Marquinhos and Atletico’s Miranda also return.
Neymar is included, with the Barcelona forward recovered from the fractured vertebra he suffered in Brazil’s victory over Colombia at the World Cup.
Squad in full:
Jefferson (Botafogo), Rafael Cabral (Napoli); Alex Sandro (Porto), Danilo (Porto), David Luiz (PSG), Filipe Luis (Chelsea), Gil (Corinthians), Maicon (Roma), Marquinhos (PSG), Miranda (Atletico Madrid); Elias (Corinthians), Fernandinho (Manchester City), Luiz Gustavo (Wolfsburg), Ramires (Chelsea); Diego Tardelli (Atletico Mineiro), Everton Ribeiro (Cruzeiro), Hulk (Zenit), Neymar (Barcelona), Oscar (Chelsea), Philippe Coutinho (Liverpool), Ricardo Goulart (Cruzeiro), Willian (Chelsea)
