Hmmm... Exceptionally generous to United, I would have said.
“Interfering with an opponent” means:
preventing an opponent from playing or being able to play the ball. For example, by clearly obstructing the goalkeeper’s line of vision or movement
making a gesture or movement which, in the opinion of the referee, deceives or distracts an opponent
• the opponent must be reasonably close to the play so that the blocking, deceiving or distracting makes a difference
