My friend, VAR is limited by their own constraints. There's a reason why that couldn't be corrected. Because it wasn't in the box. Simple as that. The only time a handball outside the box can be seen and corrected is if actually leads to a goal or a penalty. That didn't happen here, so they couldn't correct that error. I know, it's stupid. VAR is stupid. I get that you and many others are saying that it prevented a goal scoring opportunity so it should have been corrected, but unfortunately that is not what VAR allows. Whether or not it prevented a goal scoring opportunity is subjective and impossible for them to factually know for sure. Since the handball occurred outside the box, it was not considered in their minds a goal scoring opportunity. I know, it's stupid, but they have created these stupid guidelines which limits what they can do in situations like this.
Should they have simply given the free kick following a VAR review? Of course, that would be factual, simply and logical. But their own criteria and self-confusion about what they're allowed to do prevented them from doing that. Don't you get it? VAR is bent, it can't get out of its own way.
Had they given a red card, then it would have been a free kick outside the box. That's the only way that could have resulted in a free kick, at least according to their own criteria!
In my view, the reason why so many people are claiming it should have been a red card, is due primarily to that being the only way for them to have given a free kick following a VAR review, which is bent beyond belief! But that's VAR for you. On the other hand, I get that you also genuinely believe that it was deserving of a red card, because it stopped a goal. but that is hugely open to interpretation and I disagree with that. IMHO it should have been a free kick, not a red card or a yellow in my view due to it being on the edge of the box. But they couldn't give it without giving a red card, which is bent.
