Brazil head coach Tite said he was told to shut up by Argentina captain Lionel Messi in the friendly clash between the South American rivals.
"I complained because he [Messi] should have been shown a yellow card and he told me to shut my mouth and I told him to shut his mouth," Tite said. "And that was it."
Tite added: "I don't want to answer anymore on it. You need a strong referee because he'll swallow you… It should have been a card, I was right to complain."
Messi's goal condemned Brazil – who have struggled since lifting the Copa America trophy – to their fifth consecutive match without victory.
