Yeah, he always chooses the version of events which defends the decision that's been made. But that's the whole Catch 22 with VAR. Football fans cling to this misguided notion that incidents like these can somehow be interpreted on a factual basis, without any need for interpretation or subjectivity. Which is a nonsense Almost every call is subjective and will be interpreted differently by different people. Especially people with skin in the game, such as fans and managers. Which is why the whole thing has got so incredibly toxic now we've been mis-sold VAR as a tool to remove subjectivity.
That is the problem you can't remove the subjectivity from most of the decisions in football, even under video replay alot of penalties and red cards have people arguing about what is the right decision. Even offsides are controversial because they are trying to be so arbitrary about a law that was never meant to be so arbitrary you could say the same about handballs aswell.
It also doesn't help that the VAR is always going to subconsciously biased towards the onfield referees decision. Which ultimately creates inconsistency.
The whole VAR system is broken and currently mis-used. Perhaps rather than basically re-refereeing games which is what is happening at the moment. We need to take the cricket idea of giving the teams the ability to review certain decision. Maybe allow them two a game each to be called by captain or coach within a certain time (e.g. 30 seconds)of said decision.
On Top of that to remove any possible bias from the VAR we should probably have two compleatly separated VAR's who are also compleatly detached from the game and the onfield ref. They don't know the score, what has happened in the game or most importantly what the onfield refs decision is. All you do is show them the incident in question and they make what should an unbiased decision based on the video evidence alone.
Is the VARS return a split decision e.g. one says penalty and the other says no penalty then we go with the onfield decision because clearly there is no clear or obvious error. Obviously if they both decide the opposite to the onfield ref then the onfield refs decision is overturned. And if they all agree we obviously stick with the decision.
You could use it for offisides aswell forget this arbitrary idea of drawing lines, it will never be perfect even the semi-automatic system has a considerable margin of error. We still let the game play on, and then if a goal is scored the linesman makes his decision as usual, the VARS again unaware of anything including the linesman's decision watch the incident in full speed and then get to see the still frame closest to when the ball was released, then they make there decision and same as above in regards to split decisions etc.
I don't think it can carry on as it is. Its ruining the game IMO and if anything it's creating greater scrutiny and more controversy than pre VAR. Pre VAR there was an acceptance that the referee will make mistakes there only human after all. But some teams and managers are demanding perfection which is impossible with all the subjective decisions.
