Well yes, this is the real point.
So if MOTD were running VAR, they wouldn't have given the penalty, because it's not VAR's job to overturn a subjective decision.
As I’ve said for years, VAR should never have been introduced as football is too subjective. Fouls, handball, even offside, people will always have different opinions on all of these things.
No matter how many rule tweaks they make - VAR will never work.
It would have worked if anyone with a brain was in charge of it. So it can be fixed.
They could run a training session with the refs - if they got them all together in a room (and blew it up) and showed them the footage of many of these decisions, and asked them each (without conferring) to give a percentage as to how sure they are something is or isn't a penalty, then look at the results together, they'll find they're overturning decisions where half of them don't think it's a penalty, and half of those that do are not at all sure.
I like that Howard Webb seems keen to improve things, but so far it's not working. They don't know what they're doing.
