You're wrong. Auomatic review is already implemented in other sports and no one doesn't celebrate because "it might get disallowed".
You'd be better off cancelling your season ticket ASAP if the above is really what you think of VAR.
I am telling you that it will only take one or two instances of fans celebrating like lunatics, then being burnt 30-seconds later when the referee disallows it, for them to be hesitant of celebrating goals like Rashford's yesterday.
I'm not saying grounds will be quite.. far from it. I'm just saying we now have to wait and wait for goals like that to be officially given and that wait will cause hesitiation of enjoyment.
This is obvious.
It hasn't happened yet because we are at the very start of VAR, but after a while we'll get used to the fact that a goal isn't officially a goal until the referee has pointed to the half-way line.. and now, because we use VAR, there is a delay of about 30-seconds for goals like Rashford's yesterday to be officially awarded. Once we get used to this, and fans become more conscious of this, there will inevitably be a more diluted recation to these types of goals.
VAR is not a good tool for the enjoyment of the spectator.. whether in the ground or watching on TV... it will inevitably - once we get used to it - delay the live reaction.
See Man City's last-gasp goal against Spurs in the CL last season... GOAL - wild celebration - 30 seconds later utter despair because it's disallowed.
Well.. by late November this year, that will have happened a dozen or so times in the PL and then it will eventually seep, slowly but surely, into they mindset of the fan that they have to wait for the referee to allow the goal before it is officially awarded as a goal. SO, in instances like Rashford's goal yesterday, the ball will hit the net, the fans will celebrate but there will be discussions of 'that was off, wasn't it? VAR is going to call that offside". and then wait, wait, wait....
I have absolutely no doubt about this whatsoever. Once we all get use to VAR - we will get used to having to wait on confirmation of the goal. You don't want to be celebrating like a lunatic if in the back of your head you feel VAR may overturn a goal 30-seconds later.
