Brazil have named former player Dunga as their new coach for the second time.
Dunga was the captain of Brazil’s 1994 World Cup-winning team and coached the national team from 2006 to 2011.
“I am immensely happy to be back,” said the 50-year-old, who was the favourite to land the job.
Meanwhile, Argentina coach Alejandro Sabella, 59, will decide his future next week after his side lost 1-0 to Germany in the World Cup final.
Members of the squad have said they want Sabella to remain in charge for the 2015 Copa America in Chile.
“It’s down to whether I feel strong enough to give 100%,” said Sabella.
