That was a horrible call. And then it wasn't overturned by VAR, which the color analyst thought would happen, and which I thought should happen. The defender got the ball on a slide tackle. His clipping of the attacker on the follow-through was incidental, and unavoidable. If the defender had missed the ball, or had got the attacker before the ball, then the call was good. As neither of those things looked to be the case in real time or on replay, then IMHO, the call was terrible.
And then a West Ham defender got a red card after the call, so while the GK blocked the PK, West Ham will play the rest of the match down a man. smh (I don't care who wins. I just want to see good soccer AND a well officiated match.)
