Phil Foden scored twice as Manchester City came from behind to beat Manchester United 3-1 on Sunday and close to within one point of Premier League leaders Liverpool.
Erling Haaland also struck in stoppage time to leave the title race perfectly poised ahead of City’s trip to Liverpool next weekend.
Marcus Rashford’s wonder strike had fired United into a shock lead at the Etihad.
Haaland was then guilty of a miss that will go down in Premier League folklore when he fired over with an open goal just before half-time.
Foden ensured City did not slip up in the title race as he blasted into the top corner to level and produced a composed finish 10 minutes from time.
Haaland then rolled in his sixth goal in four Premier League derbies against United to atone for his earlier miss.
An 11th league defeat of the season for United leaves Erik ten Hag’s men 11 points adrift of the top four with 11 games remaining.
The former Ajax boss was furious that City’s equaliser was allowed to stand as he claimed Rashford had been fouled at the other end seconds earlier.
But United could have few complaints after being thoroughly outplayed by their rivals for almost the entire match.
Rashford rounded on his critics this week as he hit back at questions of his commitment.
The England international has been a pale imitation of the forward who scored 30 goals last season for most of this campaign but showed a glimpse of the quality he is capable of to open the scoring on eight minutes.
City pleaded in vain for an offside flag against Bruno Fernandes and he layed the ball back for Rashford to smash in a stunning long-range effort off the underside of the bar.
Pep Guardiola’s men dominated from that moment on but were kept at bay for nearly an hour by wayward finishing and some fine goalkeeping by Andre Onana.
