Iran boss Carlos Queiroz confronted a BBC journalist regarding what he felt was tough questioning.
Quieroz, whose side lost their first World Cup group stage game to England 6-2, will take on Wales on Friday.
BBC journalist Shaimaa Khalil asked Iran striker Mehdi Taremi if he had any messages for protestors back home.
Queiroz, 69, said in response: “Why don't you ask to Southgate these kind of questions? I am talking with you. I ask the pleasure to talk with you.
“I am asking one thing to you now the press conference is finished. Do you think it is fair also to ask other questions to other coaches?
“That is the only question I make. Why don't you ask the other coaches? Why don't you ask Southgate: 'what do you think about England, the United States and Afghanistan?"
