2011: Manchester United 1-6 Manchester City

Manchester City inflicted Manchester United's worst home defeat since February 1955 as they thrashed the champions in ruthless fashion to go five points clear at the top of the Premier League.

Mario Balotelli handed the away side the lead in the Manchester derby before Jonny Evans was dismissed just after the break. 

Balotelli got his second of the match and Sergio Aguero added a third to put City in the driving seat. 

Darren Fletcher pulled one back for Sir Alex Ferguson’s side but it didn’t stop City who completed the rout with a goal from David Silva and an Edin Dzeko brace. 

The result left City at the top with 25 points, five clear of United in second.
