It's nine years to the day since Manuel Pellegrini's men blew away David Moyes' visitors to claim the bragging rights in the city.
It was a pivotal win on the way to our second Premier League title in three seasons, and one fans remember to this day.
Sergio Aguero got the scoring going, turning home Aleksandar Kolarov's drilled cross. Yaya Toure made it two by poking home a loose ball from a corner. Aguero got his second and City's third in the second half before Samir Nasri's volley made it four.
A consolation goal from Wayne Rooney was not enough to dampen spirits at the Etihad Stadium.
