Before the tournament began, Maradona suggested that the game's greatest-ever player belonged in a museum.
But the Brazilian has made it quite clear that he doesn't have much time for the Argentine's abilities as a manager.
And he also launched a verbal volley at Dunga, complaining about the Selecao's current style of play.
"What kind of football is that which tries to control the game with a forward?" Pele said in reference to Argentina in an interview with German newspaper Der Tagesspiegel.
"I don't have a problem with Maradona, I just do not think he is a good coach. He has an outlandish lifestyle and rarely is that a positive thing for the team."
Turning to Brazil, Pele said that he does not agree with the current team's somewhat negative outlook.
"I myself was a forward and I always wanted to score goals," he said.
"That was the most important thing, because it encouraged the fans. The current team on the other hand plays on the counter-attack, it does not control the ball well.
"The will and the domination to control the opponent and have the ball are no longer there."
However Dunga will point to the fact his team are still unbeaten in the tournament, and comfortably defeated Chile 3-0 in the second round.
