Manchester United ended a torrid run of results against rivals Manchester City by swatting them aside in a 4-2 victory at Old Trafford.
Louis van Gaal's men have now won six games in a row after their latest win, whilst City's dreadful form means they now sit four points adrift of the Red Devils.
It all started so well for City, with Sergio Aguero turning the ball home from close range after great work down the left hand side by David Silva.
That's as good as it got for Manuel Pellegrini's side though, as United ran riot after that. Ashley Young bundled the ball home to draw United level, before Marouane Fellaini was left unmarked at the back post to plant a header past Joe Hart to give United the lead.
Juan Mata rolled home a third after being played in by Wayne Rooney, and Chris Smalling put the icing on the cake by turning home Young's free kick from close range.
Aguero did pull another goal back for City late on but the damage had already been done, with United continuing to impress under van Gaal.
On a memorable day at Old Trafford, here are some of the best pictures from the Manchester derby - with differing emotions for the two sets of players and supporters.
