Dunga has been named successor to Luiz Felipe Scolari as Brazil coach, following the country's World Cup demise
Brazil live updates
Neymar marked his first game as captain by scoring the only goal as Brazil beat 10-man Colombia 1-0 in Miami.
The 22-year-old was wearing the armband in the absence of Thiago Silva and scored in the 83rd minute to hand the Selecao victory in the first match of Dunga's second spell in charge.
Philippe Coutinho and Marquinhos among the new names in the Brazil squad named by Dunga at the start of his second spell.
Coutinho has been called up to Dunga's first Brazil squad. He's won just 1 cap for his country, way back in 2010. http://t.co/8hoa6tWRj1
Brazil will reveal the identity of their new coach on Tuesday, the Brazilian Football Confederation has announced.
Luiz Felipe Scolari stood down this week after the hosts could only finish fourth at the World Cup, having been thrashed in their semi-final 7-1 by eventual winners Germany, and then beaten 3-0 by Holland on in the third-place play-off.
The announcement comes on the back of the appointment of Gilmar Rinaldi as Brazil's general coordinator, with responsibility for all levels of the national team.
Dunga, who was in charge of the Selecao from 2006 to 2010, is reportedly the front-runner for the post.

Something wonderful happened after Brazil's 5-0 win against South Africa last night.
When the young South African boy, above, invaded the pitch at full-time and began to be dragged off by stewards, Barcelona forward Neymar took him under his wing, introducing him to Brazil's superstars and posing for photos.
So, the moral of the story is... if you're a young boy and would like all of your dreams to come true then try invading the pitch.
