Overuse of VAR means nobody knows what is going on - Queiroz
Iran coach Carlos Queiroz lambasted what he said is the overuse of video review at the World Cup to overturn close and debatable calls instead of being limited to only correcting obvious mistakes.
In the past, the Portuguese was an outspoken proponent, but now he's seeing problems with the implementation of the video assistant referee, or VAR, system.
"It's a natural human thing when people make mistakes. VAR was not born to copy human mistakes. VAR was born to make it right," said Queiroz, whose team had a goal overturned by video review in a 1-0 loss to Spain.
"So, it's not human to implement the system and come out with the same excuses that we had before. This is a question of principle."
The system, he added, should only be used to change "clear and obvious mistakes".
Saeid Ezatolahi's goal against Spain on Wednesday was overturned after the video assistant referee signalled that a player was offside. There was a long delay before the decision.
Had Iran managed a draw with Spain, they would have been level with Portugal atop the group with four points and Spain would only have two points. Iran are bidding to progress to the knockout stages for the first time in their fifth World Cup.
In the minds of Queiroz and his players - not to mention a member of Iran's staff who was hospitalised after the goal was overturned - VAR effectively changed a debatable, judgement call, not an obvious mistake.
"It's crucial and fundamental that a group of intellectual people are not intellectualising the game behind the scenes (and) nobody knows what's going on. This is not good for the future of the game," Queiroz added. "The game must be clear. Everything must be obvious."
Queiroz said he was hesitant to criticise the system because "it sounds like excuses", but he insisted that in this case, he felt the urge to speak out because of the size of the World Cup's audience.
"The people deserve to know what are the rules of the game because this is a game of the people," Queiroz said, adding that if he is indeed punished for speaking out, "I'll be here to try to swim and survive."
The replay system also has been a talking point in Portugal's matches, particularly after Spain's Diego Costa appeared to push Pepe during the teams' World Cup opener, which ended in a 3-3 draw.
The Portuguese asked for a review and were not given one, but Pepe didn't seem all that bothered by it, even though he remains convinced he was pushed.
"I believe the (VAR) hasn't really harmed Portugal or any sides that have played Portugal," Pepe said.
