I would have liked it to have been a penalty as much as anyone, but the laws were interpreted correctly, first by Oliver, and then by VAR. As bizarre as it may look, and as much as many may not like it, it was not a penalty, but a foul on Partey. Incidentally it was the same VAR team that overruled the on field offside decision for Stone's goal, when at 1st glance nobody would have disagreed with the initial offside. So it’s fair to say, that they do have some modicum of knowledge of the laws of the game.
