Manchester City demolished United 1-6 at the Old Trafford

Mancini's side achieved a victory with no precedent. Manchester City crushed Manchester United 1-6 at the Old Trafford and gave Sir Alex Ferguson the "worst day of his career".

"Super Mario" Balotelli and Edin Dzeko netted two great goals each. Sergio Agüero and David Silva completed the historic win at United's home.

Darren Fletcher scored the only goal for the "Red Devils", and even though it was a brilliant one, that was not enough to avoid one of the most terrible loses in Manchester United's history.

Jonathan Evans saw the red card at the beginning of the second part and this fact helped Manchester City dominate the offensive actions.
