After a thrilling triumph against Tottenham and a solid point at Old Trafford, Arsenal came down to earth with news the defender Rob Holding will be out for the season through injury and a tabloid exposé that showed several players apparently taking nitrous oxide.

A club representative said: “The players will be spoken to about this and reminded of their responsibilities as representatives of the club.”
