They really have bungled this haven't they? I think football's biggest issues, as far as officiating goes, is when the rulemakers try and make an 'absolute' law.
For example, we have the farce in the Champions League whereby any time the ball hits a hand its a penalty.
The same applies to the "if there's contact, we won't overturn it" rule with VAR. By that logic, every single review for a penalty NOT given should result in a penalty if there's any contact at all...and that would clearly be ludicrous.
Everybody watching knew that was a dive today. The officials at Stockley Park knew it was a dive, the players knew it was a dive, everybody watching at home knew it was a dive, the pundits all knew it was a dive...and yet we all also knew it would never be overturned because Casemiro's toenail flicked Neto's sock.
Football is a game of opinions and interpretation. I understand rulemakers have tried to ensure consistency by ensuring referees apply hard and fast rules but it's made the problem even worse when you throw VAR into the mix.
