The 50-year-old is embarking upon his second spell in charge of his nation but provoked the previous regime when he claimed that Brazil must "toughen up" in the wake of the frequent emotional reactions from the players during the tournament this summer.
Dunga also criticised Neymar's perceived focus on marketing, singling out the attacker's decision to wear a hat with his own logo on it during an interview rather than sport the team crest and colours.
Carlos Alberto, who led the Selecao to the World Cup title in 1994, has swiftly defended the Barcelona star and insists the emotive singing of the national anthem should be praised - just as it was during the Confederations Cup.
"I agree with him [Dunga] when he says that, perhaps, excessive emotion might have taken the focus out of what was really important. But it's not a matter of agreeing or disagreeing. It's a moment thing," he told Extra. "At the Confederations Cup, it was great, it was wonderful. Now, not so much. Where's the truth?
"The marketing behind Neymar did not get in the way," he went on. "Neymar was involved in absolutely everything, all the time. He was dedicating himself in training, he wasn't shying away from work and he's not the type of player to sit quietly at the medical department.
"And he wasn't stepping out on the pitch to play or to train wearing a hat. I swear to you I don't even know when was it that he wore a hat."
Brazil crashed out of the competition after suffering an embarrassing 7-1 loss to Germany in the semi-final and then succumbed to Netherlands in the third-place playoff, yet Carlos Alberto does not feel the Selecao flopped entirely.
"We were certainly not a 10, but not a zero either, because we made it to the semi-finals, which hadn't happen since 2002," he explained. "I'd say we were from medium to good."
The 71-year-old also reiterated that he has now retired from coaching and is not actively seeking a new post.
