Manchester United host Arsenal this weekend in an eagerly-awaited encounter, and the trash talking has already begun in earnest ahead of one of English football's great modern rivalries.
Arsenal travel to Old Trafford reigning supreme at the top of the Premier League, five points ahead of their nearest challengers, and having just recorded an impressive victory against Liverpool.
Manchester United, meanwhile, have endured something of a mixed start to the David Moyes era at the club, and last season's champions find themselves eight points adrift of the Gunners after only 10 games played.
Victory for either side on Sunday not only serves as potentially pivotal in the race for the title but, as always, offers the opportunity to secure bragging rights for one lucky set of supporters.
Manchester United and Arsenal fans certainly fail to see eye to eye, and a particular supporters group representing the former have stoked the flames before meeting Arsene Wenger's side.
FullTimeDEVILS, led on this occasion by comic Ian Smith, have posted a tongue-in-cheek YouTube clip picking out 100 reasons to hate Arsenal, ranging from Arsene Wenger's coat to pretentious floodlights at the Emirates Stadium.
Smith also claims that 'everyone prefers Tottenham' and laments the Gunners for their treatment of Ashley Cole.
Watch Ian Smith going at it in the video above.
