In honesty I haven't seen it but the initial description of it going past the player on the way out and most people not actually noticing anything sounds like one I'd be unhappy about if it was my team. Can't blame VAR for this though, that just gives the ref the opportunity to review a decision. What he then decides is up to him.
Not watching but reckon you're all mistaken, var was brought in to make sure the big and defining decisions in the big games were correct.
why is it? He's not standing there with his arms at his sides and had the ball blasted at him, he's jumped towards the ball and put his back towards it and left his arm there.
