Weeyin, I dont think that referees are corrupt but they can make mistakes, be influenced by crowds/managers and will have a fear of getting abuse in the media for giving wrong decisions again the bigot brothers but if they can ask for a review which clearly shows the incident, then the pressure is off them.
If the review is unclear then the original decision stands and we can all argue over it but it will cut down on wrong decisions, players caught cheating will be instantly penalised and as such the temptation to cheat will be greatly reduced, giving us a more fair game to watch. As such VAR is a no brained for me.
