He couldn't though, and that is my problem. He had moved his right foot so far unnaturally right he really couldn't do anything with the ball, from the body shape he was left in he just couldn't open himself up to pass the ball or make a shot. Had it just been a subtle move of his right leg to the right I would agree with you, but it was so exaggerated it has all kinds of alarm bells ringing.
I'm with others on this though, if we can't agree as referees whether it was a penalty or not VAR should have been leaving well alone. Perhaps my background as a defender is why I don't think it was a foul is influencing me, perhaps others who do think it was a foul were attackers, as would appear to be the case with Richards and Shearer.
