Manchester City sealed a straight 3-0 win over Manchester United to keep stride with Tottenham at the top of the table.
The Citizens dominated from start to finish and sealed the win thanks to an Erling Haaland twofold time 26′ and 49′ and one from Phil Foden 80′.
It could have been so many more had Andre Onana not pulled off a succession of excellent saves.
City were sublime and ran riot against a team that look lost.
City once feared a trip to Old Trafford but painted the town blue once more with the victory over a demoralised United on Sunday to reassert their dominance.
Pep Guardiola’s treble winners are third in the standings on 24 points after 10 games, two points behind leaders Tottenham Hotspur. United, whose defeat was their first in four games in all competitions, are eighth with 15 points.
United have lost six of the last eight matches against their local rivals, including a 2-1 FA Cup final defeat last season.
