I'm not really into the conspiracy theories that suggest the officials are trying to make sure City don't win it or Arsenal do (although there are enough examples now of when things have gone against us in matches in recent seasons to make you ask the question).
But it's not inconceivable that those in the VAR shed can hear what the likes of Neville are saying...things like
"Definitely a foul, they can't give this, they have to disallow it, they need to look at xxxx, it will be ridiculous if they allow this to stand etc. etc.", or actually pointing out specific points or challenges that might not have been immediately obvious to the VAR team.
Sky provide the cameras so it's more or less a given that they can hear the TV commentary if they wanted to. We all know Neville is biased, it's not a point he even tries to hide. So who is to say they don't hear him say "There's an arm around Raya's neck there, they have to disallow this". Ultimately they're human and humans can easily be influenced what others say, even subconsciously. So in other words they might be reviewing a different incident entirely and are then drawn to whatever Neville is saying.
For me, the whole point was it took 37 reviews and nearly 5 minutes to reach a decision, and that fact alone proves beyond any doubt that it wasn't a clear and obvious error. It doesn't take that much scrutiny to find a clear and obvious error, they were clearly looking for a reason to disallow it. The constant delays proved that's the only foul they were actually considering too. How much more proof do you need?
