The former Selecao coach has spoken of his joy at taking charge of the club he represented twice as a player, and replaced former boss Fernandao
Dunga has been named as coach of International, his first role since being fired by Brazil at the end of 2010 World Cup.
The former Selecao captain led the national team for four years, winning the Copa America in 2007 and the Confederations Cup in 2009, but was sacked after a quarter-final exit to Netherlands in South Africa.
"The most important thing is to put the ideas into practice. I want a vibrant and competitive team," Dunga told reporters at his unveiling.
"Inter have a battling team and in football we can always learn."
Dunga, who had began and ended his playing career with International, went on to voice his opinion that he had landed one of the most exclusive roles in the game.
"The International job is like the Brazil job; you do not go when you want, you go when you are called," Dunga said.
Club president Giovanni Luigi chose to replace former boss Fernandao with Dunga after watching the club finish ninth in the recently concluded Brasileiro.
