The best way forward with VAR is to give the managers/coaches a chance to challenge a decision based on the match officials not seeing it live, even after the final whistle the clubs can challenge a decision and results changed, if you got more time to review something after the game then if it means getting the right decision, why not,
but the one big moan is the handball rule ? Ball to hand is not a foul ? How can you jump and know the ball is going to come off somebody and then hits your hand or arm, city goal with by rodri and mahrez jumping to challange and the ball coming over his should is never in a million years handball, also for our pen their lads knows fuck all about where the ball is ?
