Dunga has been appointed as Brazil coach for a second time following the resignation of Luiz Felipe Scolari.
Luiz Fellipe Scolari resigned following a "disastrous' world cup spell that saw Brazil falling shamefully to a brilliant Germany side. Scholari's side went on to lose to Luis Van Gaals dutch side (3-0).
50-year-old Dunga was sacked by the Brazilian Football Federation (CBF) after Brazil were knocked out of the 2010 World Cup at the quarter-final stage, but has been given another opportunity to lead his country.
Dunga, captain of the Brazil side that won the World Cup in the United States 20 years ago, was unveiled a press conference on Tuesday.
