Dunga wary of Colombia quality ahead of next month's international friendlyDunga previously managed Brazil from 2006 to 2010
Brazil head coach Dunga says he will face a baptism of fire when his second spell as boss gets underway against Colombia on September 5, insisting that their South American counterparts have grown into a genuinely good international outift.
In an interview with CBF TV, 1994 World Cup-winning captain Dunga said: "With their Argentine coach (Jose Pekerman), Colombia has grown significantly in recent times."
"They have achieved a tactical discipline and we all know how strong they are technically. They have many players in Europe that have helped Colombia improve as a team. They showed that at the World Cup."
Dunga will name his first squad of a second era on August 19 and added: "After the World Cup, we are all looking forward to the return of the national team."
"We know the responsibility that Brazil has to both win and put on good performances. This is the challenge of assembling a competitive team."
"I'll select a blend of youth and veterans, with new blood that should increase our competitiveness. I don't want anyone to think his place is safe."
