Animated hand gestures, patrolling the area outside his technical area and, of course, arguing with a fourth official: Mikel Arteta was back.
Back like those VAR-related comments after Newcastle’s winning goal on Saturday had never been made, and back like a letter from the FA asking him to explain his actions was not on its way.
It took just one minute for Arteta to spring to life off his bench, head in hands. Kai Havertz, from a Gabriel Martinelli corner, had headed the ball into the ground while alone in the box.
