City dominated from the very first whistle, and after Edin Dzeko put Manuel Pellegrini's side ahead after just 43 seconds, there only ever looked to be one winner.
The fastest derby goal recorded since 1968 and the quickest ever away goal at Old Trafford, the Bosnian's strike set City on their way and after he added a second after half time it only required a late Yaya Toure effort to add some much-deserved gloss.
The Blues had done the double over their cross-town rivals for the second time in three seasons, and sent out a powerful warning shot to league leaders Chelsea to move within three points of the summit - while still retaining two games in hand.
