Man City 4-1 Man United (March 2004)
It turns out City knew how to humiliate their local rivals long before Sheikh Mansour’s takeover.
It came in the dying stages of the 2003/04 campaign, where United hoped to keep their slim hopes of retaining their Premier League crown alive. However, Robbie Fowler’s third-minute opener put City ahead.
Jon Macken then smashed home his volley into the net to put the hosts into a two-goal lead. And, while Paul Scholes’ brilliant 20-yard hit briefly gave United hope, Trevor Sinclair restored City’s advantage.
Shaun Wright-Phillips then beautifully scored the fourth goal to seal a shock defeat for Ferguson’s side.
