Irmatov was selected as a referee at the 2013 FIFA Confederations Cup. In the Group A match between Brazil and Italy on 22 June, he blew his whistle to award Italy a penalty and was seen pointing at the penalty spot. A second later, as play continued, Giorgio Chiellini scored with a low shot, with Irmatov instead pointing to the halfway line to signal a goal. Irmatov admitted to his mistake after the game saying: “While I was whistling for a penalty, out of the corner of my eye I saw the goal and I thought advantage should be played and gave the goal.”
