It just turns it into pantomime farce. I assumed he had played the advantage. You've played the advantage, the goal is scored, so why then pull it back after the event? If he hadn't played the advantage and stopped it for the foul then why didn't he blow for the foul straight away?
Mark Pougatch summed it up, how can a player get a red card for denying a goal scoring opportunity when the ball ends up in the back of the net? It's just stupid.
What angered me is what if they had gone up the other end and scored? And it still might be significant at the end of the season.
Have to say though there were two or three occasions when Cherki should have passed to Haaland.
