Trouble is that will never work with a competition like the FA Cup because in the 3rd round there are 32 matches and and there would need to be numerous camera positions at each match (in fact they would need the same amount of cameras at each match to make it the level playing field you...
Wouldn't necessarily disagree about the ref reviewing them, particularly the Man Utd one where there was a suggestion that Lukaku was offside and impeding the defender before the trip on Mata but I guess that is down to the communication between the two?
I don't know for sure but I'm guessing that at the 9 games selected for VAR there had to be access to a monitor otherwise the system cannot work. Whether that was pitch side or just down the tunnel is irrelevant. It might not be as obvious as the ones in the world cup.
No worries. Understand why you said what you said but I think it's now a case that the ref's are trusting the VAR more.
One of the things I think is being looked at is how the VARs cope with multiple games at the same time, ie the VARs are at a central location. In the world cup there was...
You're wrong, not all decisions in the world cup were reviewed by the referee on a monitor, that's just your perception. In the group stages there were 17 reviews of which 14 were reviewed by the ref on a monitor and therefore 3 weren't. At that time more might have been reviewed as weren't...
Should be but how hard is if it for 3 on field officials (and why not include the 4th official as well) to spot when players encroach. For example, the 4th official could quite easily move level with the edge of the penalty area, the ref level with the ball and the lino level with the goaline...
But from what happened yesterday you've come to the conclusion that they are operating the system differently to the world cup. The ref has accepted what the VAR has advised him and changed his decision based on that.
My understanding is that there the VAR can tell the ref he got it wrong or he can tell him that he might want to review the decision. It may be in the examples you have given the ref accepted the description given by the VAR. If he hadn't, he could review the footage.
Not sure it has anything to do with technology other than tv cameras. GLT is completely different as there are fixed sensors around the ground to identify when the ball crosses the line. VAR is just about watching replays.
