I don't think its a conspiracy against us - and to be fair we've had a few very dodgy VAR calls go our way (Sheff Utd and Norwich offside goals spring to mind).
However...some of those that have gone against us are ludicrous in the extreme.
Kane goal vs Sheff Utd
Moura is fouled and pushed over, and as he is falling the ball hits him on back of the shoulder. Ball breaks to Kane and Kane scores. Goal is given by the onfield ref, but VAR then decides it was handball by Moura. In this instance, it is far from clear what part of Moura the ball actually hit - so for a VAR to be 100% certain it hit his arm is ridiculous. To add insult to injury, the ref should then have given a freekick to Spurs, as no advantage was received - but instead Sheff Utd got a freekick for handball. Fuck right off.
Kane pushed vs Bournemouth
About as blatant a push and a penalty as you are ever likely to see. The onfield ref missed it, and VAR decided it was not a clear and obvious error. WTF?????
Son red card vs Everton
A foul by Sonny with a worse outcome than would normally happen in that the knock on effect was the Everton player got his legs caught and broke his leg/ankle. Just a foul - nothing more nothing less, but then VAR tells the ref to red card Sonny and we are down to 10 men and it costs us a victory.
Penalties vs Southampton and Newcastle.
Not penalties - simple as.
Offside goals
The issue with some of these marginal offside goals is that VAR is trying to apply a 3D view of the offside line to a 2D picture at a broadcast camera angle. It simply does not work and the margin for human error on this is huge. The worst instance of this was the disallowed Firmino goal against Villa early last season, which VAR got spectacularly wrong. Sonny being offside in the build up to the disallowed Aurier goal against Leicester was another example - but not as obvious. In my opinion the only way to fix this is to have mobile overhead and sideline cameras sync'd and tracking play all the time, as this would remove virtually all of the camera angle issue. However that is not practical.
