The ref was looking right at it during the game and was pretty close and saw nothing. Not sure how he changed his mind after VAR, Gordon clearly is moving to play the ball and Utd player runs across his foot/leg. it’s the Utd player who hits Gordon’s leg
VAR is a good tool to have but it is not being used properly. Let the officials ref the game and help them with OBVIOUS ERRORS, not microscopic offside calls, or decisions that take 2 minutes to figure out.
