Clubs, and therefore peoples livelihoods, are now so dependent on what happens on the pitch so I am generally in favour of any system that can correct obvious mistakes in key moments of a game. However, the way VAR's is being run at the moment is not what I was hoping for.
With the decision to use VAR being left to either the referee and/or some 4th official up in the stands, I believe the pressure will be on them to review more and more to avoid being pilloried for not reviewing. This in turn will lead to the game increasingly being stop start which is not what anybody wants. I think the decision to review should be left to the clubs, therefore leaving the referee to, well, referee and apply the laws of the game, good or badly
.
If VAR is here to stay I would like to see a similar system that tennis and cricket uses and give each club a set number of reviews it can use e.g. one review per half, if review successful then they keep it, if not its gone and they cannot ask for any further reviews until the next half. This should reduce the number of interruptions during a game, takes the pressure of the officials and puts the onus on the club to get the review right and not waste it for when it really matters. This would still leave lots for debate after the game :stout:
