Queiroz, 65, led the South Africa national team between 2000 and 2002 but left shortly after qualifying the side for the FIFA World Cup upon a dispute with the South African Football Association (SAFA).
Since then, he was assistant to Sir Alex Ferguson at Manchester United from 2002 to 2003 before taking the head coach job at Real Madrid for one season in 2003/04. He returned to Old Trafford to assist Ferguson again from 2004 to 2008 before taking over the reins of his home country Portugal and leading them to the 2010 World Cup.
An eight-year stint with Iran followed, where he's been lauded for the progress with the Asian nation, qualifying for the 2014 and 2018 global showpiece editions.
While paving the way for several of the players to earn moves to Europe, his overall record of 60 wins in 100 games made for impressive reading.
With Iran now ranked 22nd in the latest FIFA ranking, his appointment to replace Jose Pekerman has sparked major optimism.
Pekerman had been in the role since 2012 and took Colombia to the World Cup quarter-finals in 2014, although they lost on penalties against England in the last 16 of the 2018 tournament.
"Pekerman has left a fantastic legacy. But we are only just starting and this isn’t the time for questions," he said at his unveiling on Thursday just days after leading Iran to the semi-final of the Asian Cup.
"I don’t want to give you lots of answers because our work is only just beginning. That will come later. The path of champions starts this way."
Colombia are pooled with Argentina, Asian Cup champions Qatar and Paraguay in Group B of Copa America scheduled to begin on June 14.
