Manchester United's 10 most embarrassing defeats

#1 Manchester United 1 - 6 Manchester City (October 2011)

Probably the game that most effectively portrayed Manchester City’s elevation from ‘noisy neighbours’ to genuine challengers, the Citizens effected Manchester United’s biggest home defeat for 56 years during a 6-1 mauling, with Sir Alex Ferguson’s side conceding six goals at Old Trafford for the first time since 1930.

City went on to win the title in 2012, with Mario Balotelli’s ‘Why Always Me’ shirt helping the game earn a spot in footballing folklore.
