If they are going to change a decision based on VAR, the players, coaching staff, the crowd and the media need to respect the referee's final decision. Also, I think they could do with capping the number of VAR challenges a team is allowed to make. Say, one or two challenges per team per half. If you're successful, you keep your challenges. Most other sports with the challenge system, like tennis, cricket, NFL, limit the number of challenges a team is allowed.
