Nevertheless, the Portuguese was given a round of applause by Iranian journalists as he took his seat in the press room, having led the Asian side to a 0-0 draw with Nigeria in their World Cup opener in Curitiba on Monday.
Iran now face a tougher test on Saturday in the form of Argentina, a game described by Queiroz as "the most important match in the history of Iranian football", and Messi.
"Argentina are a great team," said Queiroz. "We have watched them a lot and they have so much quality. It's the most important match in the history of Iranian football. We won't be the ones dictating the game, but we have come here to be ourselves - to compete and fight for 90 minutes."

"We will try to stop them," he said. "We need discipline and we need to be one step ahead of Argentina. We need to focus on the next ball, the next move, the next play.
"But we can't think about playing against Messi. We will play against Argentina, against space and against time, because those are the things we can control.
"We can't focus only on Messi because Argentina also have [Angel] Di Maria, [Gonzalo] Higuain, [Sergio] Aguero and many more great players."
