A Video Assistant Referee (VAR) is the latest digital enhancement to live games. Used in the 2018 FIFA World Cup, VAR is able to ensure that the right calls are made which ultimately contributes to the fairness of the match and the satisfaction of fans.
When a potential incident occurs -- from difficult penalty decisions to mistaken identities, the referee can send a notification to the Video Assistant Referee or vice versa. The information is reviewed and then opinions are shared. Of course, the referee has the option to watch a video of the potential offense on the field. Afterward, the appropriate action is made.
The Video Assistant Referee proves to be a compact solution to the misuse of direct red cards, as well as potential goal infringement.
