Irmatov kept his cards in his pocket as long as he could but he could have given some yellows to players from both sides but in his defense, the match probably didn't need the cards.
There were two 50-50 hand balls in the Korean penalty area during the extra time but the referee decided to not award any of them even though I've seen those called.
South Korea scored at the end of the First Extra Time when Irmatov had said 1 minute of added time but the Koreans scored with 20 seconds passed that which angered the Iranians. To be fair, the added time announced, is always minimum.
