Brazil coach Dunga will once again lead the nation's Olympic team on home soil next year.
Dunga will lead Brazil's bid for Olympic gold in football for a second time after being confirmed as coach Alexandre Gallo's replacement.
The current Selecao boss combined the senior job and Olympic duties in 2008, but they could only secure a bronze in Beijing.
Mano Menezes led Brazil to the final in London three years ago, with a stellar squad including the likes of Neymar, Thiago Silva and Oscar – but the side lost the gold medal match to Mexico.
Gallo had been set to combine his role as Brazil's Under-20 coach with a role at next year's Rio games, which will likely see the hosts set as overwhelming favorites on home soil.
