On another day (for another team) one or both of those penalty incidents would be flagged by VAR and a penalty is awarded (and arguably the one on Garnacho, no idea how that wasn't deemed as bad or worse than Caemiro's). But in 26 matches now in the Premier League we've had 2 penalties and one of those when we were 6 goals down. We've had multiple stone wall penalties not only not given but half the time they don't even bother to review hem. I'm long past the point where I even expect them to review them or ever give us one. I wouldn't be surprised if we don't get another penalty for the rest of the season as it's obvious to me we just aren't getting penalties for whatever reason.
In fact the only penalty we've had this season that we gained something from was vs Palace. Which was the same game that Andre Mariner and the VAR team decided they needed to even up by picking Casemiro grabbing someone's collar out of a 20 man scuffle full of pushes, grabs and slaps and give him a red card. The same Andre Mariner that went against protocol yesterday and asked the Ref to review a decision that he'd already seen and booked someone for, which wasn't a clear and obvious error.
