Happy Demolition Derby Day... Nine years ago, City scored SIX at Old Trafford!
Roberto Mancini's men humiliated United on their own patch, condemning the Reds to their worst home defeat since February 1955 and issuing the loudest statement of our title credentials!
It was a day the Blue half of Manchester will never forget.
Always one to ignite drama, Mario Balotelli sparked City's dazzling display, opening the scoring with a cool first-half finish and revealing his iconic 'Why Always Me?' t-shirt in celebration.
Following Jonny Evans' red card, the floodgates opened. Balotelli bagged his second of the afternoon before Sergio Aguero netted his first Manchester Derby strike to make it 3-0!
Darren Fletcher pulled a goal back for Sir Alex Ferguson's side but City mounted a ruthless response.
Edin Dzeko restored our three-goal cushion before David Silva extended it to four, slotting through David De Gea's legs!
And Dzeko added the icing on the cake to make it six in injury time - he even had to ask Aleks Kolarov what the score was, as he headed over to the jubilant City fans to celebrate!
Unbeknown at the time, the result would prove pivotal in the Premier League title race, as Mancini's men pipped United to the title on goal difference in the most dramatic of finales with virtually the last kick of the enthralling campaign!
