The Gunners have rediscovered their groove after a slow start to the season.

The heavy 4-0 defeat away to Liverpool back in August prompted Arsene Wenger to mix up his tactics in order to get his side challenging to reclaim their Champions League status once again.

For all of the criticism (some deserved, some not) of Wenger, clever implementation of his squad rotation between the league and cup competitions has allowed Arsenal to not rely heavily on key players such as Alexis Sanchez and has allowed for only three defeats since the defeat at Anfield.
