At the risk of being annihilated in this thread, I suspect part of the reason the penalty wasn't awarded was because CHO didn't really benefit - if he hadn't handled it, it would have been handball by Greenwood anyhow so the arguments that it was advantageous fall flat for me. Two players have jockeyed for position shoulder to shoulder, both players' arms went up as a result of their jostling, and minor contact with the ball occurred. Calling that deliberate or that CHO was making himself bigger to prevent Greenwood getting the ball is disingenuous, especially as it fell for Greenwood anyhow.
I can empathise with your frustrations given the context of VAR and how it's been applied this season, but if the laws say that's a penalty then that's objectively ridiculous and the laws should be changed. If the contact with CHO's hand had taken it away from Greenwood and prevented him from being able to control it, then yeah that's an obvious advantage gained and a valid penalty. Don't think anyone can argue that it's a big enough advantage gained given they were at the corner of the 18 yard box with their backs to goal.
