In the seconds that followed Reiss Nelson’s extraordinary winner for Arsenal on Saturday afternoon, there were bodies on the floor, tears in the stands and, bizarrely, a child on the pitch. Such was the explosion of emotion inside the Emirates Stadium that no one seemed to notice the young boy wandering around the touchline.

It was Mikel Arteta who grabbed him in the end, leading him towards a security official as the players returned to their positions for the final few seconds of action. “I saw a kid next to me,” Arteta laughed afterwards. “It was crazy. You lose sight of where you are.”
