Arsenal fans do not have the ability to watch their side in Champions League action this season but they will have still enjoyed what they witnessed on Tuesday evening.
Arch-rivals Tottenham played host to Bayern Munich in North London and started in the ideal fashion, with Son Heung-Min firing Mauricio Pochettino's side into a first-half lead.
However, the wheels soon fell off Tottenham's wagon as Bayern Munich, led by former Arsenal starlet Serge Gnabry, hit seven past the Lilywhites to seal a historic win.
Gnabry, a graduate of Arsenal's academy, scored four of the Bavarian side's goals to increase the pressure upon Pochettino after Tottenham's stumbling start to the season.
While Arsenal fans will have enjoyed his display, they will have also enjoyed his reaction to his performance - as he quickly took to social media after the match.
"North London is RED!!!" The Germany international posted, referencing the words that are often stated by supporters of the Gunners before any derby against Spurs.
While Gnabry's haul was not as good as it would have been if he was in an Arsenal jersey, his response showed that the view 'once a Gunner, always a Gunner' remains true.
