Former Brazil midfielder Juninho Pernambucano has hit out at Dunga, comparing him to ex-France coach Raymond Domenech.
Dunga was formally dismissed on Sunday and Juninho, who announced his international retirement after the 2006 World Cup, feels he made major mistakes in all aspects of his work in South Africa.
"I'm sad but I'm not surprised [by Brazil's early exit]," he told Journal du Dimanche. "This team was flawed and the first person responsible was Dunga.
"How could he not take Ronaldinho? Even at 70%, he is better than most. He could have taken the burden off Kaka, who was not at the top of his game. Marcelo should also have been in the squad, but Dunga preferred to stick with the team that won the 2009 Confederations Cup.
"It's unfortunate that we were denied the chance to play our way. There was no design. Several players were out of position. In the World Cup, that is not forgiven.
"We also knew that Felipe Melo could crack. That's what happened. Dunga has made many mistakes. We must change everything to prepare for the 2014 World Cup. Change the coach, the technical committee, the medical staff, the press officers. We can't stay as we are."
Having spent the majority of his career with French club Lyon, Juninho said he is "sad to see France in such a state" and, asked if Dunga could be compared to Domenech, he said: "Yes. Unfortunately, they are alike.
"Dunga loves conflict - he feeds on it. His communication has been disastrous. He has brought a negative energy around the Selecao. He should let people talk but, no, he did the same as Domenech and put himself in the position of 'one against the world'.
"I think Domenech made the same mistakes as Dunga. He built a team in his own image, based more around force than technique."
Juninho also said that, while he is disappointed by the quality of performances in South Africa, the much-maligned Jabulani ball is not to blame. "I bought one and I went to test it," he said.
"The ball requires a little practice, but it's delicious. It's a poor excuse."http://soccernet.espn.go.com/world-cup/story/_/id/806217/ce/uk/&cc=3888?ver=global
