An angry Carlos Queiroz lashed out at Federation Internationale de Football Association and the VAR system after his Iran team's 1-1 draw with Portugal and elimination from the World Cup, suggesting the referee could have received instructions not to send off Cristiano Ronaldo during a VAR review for an elbow late in the game.
VAR was also used to award Spain a late equaliser in their game meaning the 2010 World Cup winners leapfrogged Portugal as group winners.
Two such decisions were in the Portugal-Iran match. "I'd have to watch it again to talk about it, but I think the VAR did its job". 20' Portugal avoid the danger after long pass from Iran player lands in the box.
Isco became Spain's 47th different goal scorer at World Cups, when the Real Madrid player equalised against Morocco.
The 34-year-old's right-footed shot, which came off a give-and-go with Adrien Silva, curled the ball past goalkeeper Alireza Beiranvand. There were some wildly speculative long-range shots, some incredulous grinning when he didn't get free kicks and corners and, nine minutes into the second half, a burst in from the left that took him past Morteza Pouraliganji before a collision with Saeid Ezatolahi.
Beiranvand saved Ronaldo's penalty to deny a Portugal 2-0 lead.
Iran coach Carlos Queiroz remonstrated angrily with the officials as Saman Ghoddos appeared to be impeded by William Carvalho inside the area.
Those in charge of VAR called the incident to the referee's attention, but the Paraguayan official, Enrique Cáceres, did not feel there was motive to send Ronaldo off.
The Portugal captain was lucky to escape with a yellow in his side's draw.
However, in injury-time, Karim Ansarifard netted an equaliser from the penalty spot to set up a grandstand finish and Team Melli even had one final golden opportunity to snatch all three points.
Mehdi Taremi could score Iran's second goal but he missed his outstanding chance in front of the goal.
