You are such a box ticker and I think deliberately miss the point.
‘Yes it is that hard’. The point clearly was why can’t you just mention to the ref that he’s missed it, since the incident is being reviewed anyway.
‘Not that hard’, Christ what an absolute jobsworth you must be, sticking rigidly to the policy no matter what and refusing to apply any common sense to the situation.
Common sense is not in the rulebook so he can't apply common sense, he can only apply the rules as they're written for him, not the ones he thinks make more sense than the rest.
As it is, a VAR is powerless regarding corner kick decisions, regardless how clear and obvious it looks. I don't think there was any review of it either. There was a check for a penalty. It wasn't a penalty, so that was the end of the check. A review is a ref at his monitor, which didn't happen. When he does that, the final decision is up to him.
Scotland will finally catch up with the world, and bring it in after the World Cup, as 41 clubs of the 42 who voted, see the benefits. So the list of leagues with it continues to expand, and the risk of it being binned off continues to fall.
