The referee’s decision to award a free kick to Manchester United leading to the goal appears questionable. If VAR was reviewing a potential penalty, it’s inconsistent to then award a free kick, essentially re-refereeing the game.
The correct decision should have been a goal kick or a corner to Man United, considering there was no foul inside the box and the defender got the ball.
The rules state that VAR can’t intervene for fouls outside the box, so it’s unclear why the referee intervened in this instance.
