If your interpretation of the job you’re tasked to do is to protect your mate out on the pitch, whereas the expectation of the outside world is that your job is to correct their mistakes I can imagine most referees will not look forward to VAR duty. What a pathetic state of affairs. Just scrap VAR, it’s clearly entirely unfit for purpose. It’s bad enough having to deal with the occasional human mistake, it’s ten times worse when that is compounded with intelligence insulting levels of mistakes being covered up by their mates in plain sight.
