One fairly minor point - but it irks me slightly every time I see it, is the way they announce a non-overturn on the stadium screens, especially for penalties not given when there's a potential foul. The screen says, for example: "No penalty. No foul."
That's inaccurate - and again, contrary to what the VAR protocol says. To paraphrase slightly, the VAR is not deciding, "Was it a foul?" but "Was it a clear and obvious error to give/not give the foul?"
As I say, it's a somewhat minor point but it does shift the considerations and the conversations about VAR outcomes. You quite often hear the pundits saying something like, "That was (or wasn't) a foul - I can't believe the VAR didn't see that." Which is to misconstrue what the VAR is actually deciding on.
I understand it might be a little tricky to find a neat, concise form of wording to put up on the screen but the way they just baldly state "No foul," when that is not what the VAR is saying, is just causing and/or perpetuating misconceptions about the whole process.
