Arsenal boss Mikel Arteta has been looking to evoke Sir Alex Ferguson's 'brutal honesty' as Arsenal prepare to face Manchester United on Sunday.
Victory for the Gunners tomorrow would put them eight points clear at the top of the league, while United can go level on points with second-place Man City with a win.
It is the most important clash between the two sides in over a decade, potentially eclipsing the Red Devils 8-2 win in the 2011 fixture that confirmed Arsene Wenger's side as a team in decline.
