How much has changed in the last 20 years for Manchester City?
But a couple of decades ago, while United were pursuing a historic treble, City were making history of their own by playing in the third tier of English football for the first time.
Ahead of the Manchester derby, a new Sky Sports documentary has looked back at City's year in the third tier of English football in the 1998/99 season.
In 'We're Not Really Here - Manchester City 1998-99', former manager Joe Royle, former chairman David Bernstein, and ex-players Shaun Goater, Paul Dickov, and Nicky Weaver reflect upon how City ended up languishing two divisions below the Premier League.
They also discuss how, in a remarkable climax to that season, they managed to stop the rot - and sow the seeds for the extraordinary era which the club has enjoyed since.
Watch 'We're Not Really Here - Man City' from 6.30pm on Wednesday on Sky Sports Main Event or Sky Sports Premier League, followed by Manchester United vs Manchester City at 7pm on the same channels.
