In the "Referee Quiz" you can play the role of an assistant football referee and test yourself in ten difficult situations. Your task is easier. You don't have to run like crazy down the sideline and pray that the sweat dripping from your forehead doesn't get into your eyes. You sit comfortably in front of the VAR screen and watch what is happening on the screen. It is from this perspective that you watch the scene from the pitch and - as befits a good video quiz - you make a binding decision.
