I think to understand what constitutes match fixing - and how possible it is to do by the refs and VAR panels, it's worth looking at the data before VAR was introduced.
So the Independent Key Match Incidents Panel reported 82% of major decisions judged correctly pre-VAR - that is up to about 93% since VAR has been deployed.
And I do think, pretty obviously, offsides will be a big reason for that increase as offsides are almost entirely not subjective - youre either on, or off, to a painfully minute level currently.
So where the biggest room for perceived error is always going to be for penalties and fouls, these are subjective incidents, and there is a huge burden on the VAR to show a clear and obvious error from the on-pitch decision.
For me, VAR has made it HARDER to match fix - fouls and anything that requires an interpretation of the law is still decided by humans - and is still subjective - nothing has changed other than it can be reviewed in real time -
So if you believe matches are being fixed, it is not only being done in plain sight, but it is being done in plain sight with more scrutiny than ever being allowed by fans and the players/managers.
Which for me means they are in on it, which basically makes this wrestling.....
