5 things we learned from Arsenal v Burnley

Mustafi is absolutely crucial

Sunday’s victory, in which he scored his first league goal for the Gunners, marked Mustafi’s 15th consecutive Premier League game without defeat.

Arsenal have lost only three games this season – one coming on the opening day of the season against Liverpool, and two consecutive defeats in December against Manchester City and Everton.

Mustafi however was not involved in any of those three matches. He did not make his debut for the Gunners until a month after the 4-3 defeat to Arsenal, and was sidelined in December, recovering from a hamstring injury.
