Mikel Arteta kicked off October by masterminding a win over Tottenham Hotspur in the North London Derby. Fast forward a month and he could inadvertently play a role in Arsenal's rivals being eliminated from the Champions League.
It's come down to matchday six in Group D to determine which two teams will qualify for the last-16 and who will finish third - thus transferring to the Europa League and potentially setting up a knockout play-off fixture against the Gunners when the competition resumes in the new year.
As things stand, any one of Spurs, Sporting Lisbon, Eintracht Frankfurt or Marseille can reach the Champions League knockout phase. In fact, Antonio Conte's side know they just need a point to secure their place alongside the likes of Manchester City, Liverpool, Bayern Munich and Real Madrid in next Monday's draw.
