I don't get why VAR was needed for the penalty? You can't run up then stop; fainting then taking it is ok, a la Aldridge, but you cannot come to an absolute stop like Son did, and you can't hold hands with two of your players before it's taken (i.e. two Spurs players were stood right next to him when taken because they had no idea what he was gonna do so obviously went to follow it up!).
Didn't see the actual foul for the pen, but heard it started outside of the box, so why was it a penalty? It's always been where the foul is first committed, no?
