As the build-up to the weekend’s big Premier League clash gains momentum, Arsenal and Man United fans have been trading insults online.
However, one set of supporters have gone that extra bit further.
As world football eagerly awaits United's trip to the Emirates and the battle between struggling managers Arsene Wenger and Louis van Gaal, a Youtube channel for United fans has released a video poking fun at Arsenal's support, or 'Gooners' as they are known.
Full-Time Devils sent their reporter from Manchester to London to discover what it really means to be an Arsenal fan.
According to the skit, the top tips for being a Gooner include; being fickle in support for the manager, paying high ticket prices and, of course, not seeing contentious incidents that go in favour of their team.
Strangely, in his extensive research on the subject, Mancunian presenter Ian Smith could not locate any of Arsenal's fourth-place trophies glistening in the Emirates trophy room.
