Arsenal's Premier League title push has been impressive this season, but perhaps the past few games have shown where they have to improve to stay at the top for years to come. Without a win in four, the Gunners have seen their lead cut to just two points, with rivals Manchester City holding two games in hand.
It looks more likely that the current champions add yet another to their cabinet unless there's a dramatic drop off in their own form, meaning lessons must be learned about where points have been dropped by the Gunners. The side haven't gone perfect this season, which is no sin, but there are places to improve.
Perhaps one of the main areas is the tools that Mikel Arteta has available to solve multiple problems in many different ways. The Spaniard has that in attack this season, with Bukayo Saka, Gabriel Martinelli, Emile Smith Rowe and Reiss Nelson all able to cause problems on the wings.
