While Manchester City will not collect the Champions League this season, their points total will once again put them among the greatest sides in the history of the Premier League.
And like 20 years ago, a team from Manchester could collect silverware from three of the four competitions they entered. Manchester United won the Premier League, the FA Cup and the Champions League, while City already have the League Cup and are in the FA Cup final.
But how do both teams compare? Sportsmail has taken a look at both and rated them below.
Sir Alex Ferguson won the treble while Pep Guardiola has led Manchester City to new heights
Manchester United 98-99
Peter Schmeichel – 9
Probably the best goalkeeper in the world at that stage and changed the game with his ability to close down people one-on-one.
Gary Neville – 8
No-frills right back who was a reliable, dependable cog in Sir Alex Ferguson's side.
Jaap Stam – 9
A colossus at centre half and added some steel to the back line – his departure would later be Ferguson's biggest regret.
Peter Schmeichel was probably the best goalkeeper in the world during the 1998-99 season
Gary Neville and Jaap Stam were integral parts of United's defence that campaign
Ronny Johnsen – 7
No one would pick him out as a star of the side but he played a key role throughout the campaign.
Denis Irwin – 8
Much like Neville, offered solidity on the left and a foundation for the attacking thrust of the rest of the side.
David Beckham – 8.5
Lost amid the glitz and the glamour off the pitch is just how talented Beckham was on it. A wand of a right foot.
Roy Keane – 9
Now the world's angriest man but was once just the world's angriest footballer. Offered steel in the middle of the park and sly quality.

Paul Scholes – 8
The myth of Scholes since his retirement vastly outweighs the reality. Even so, was an impressive player and starred this season.
Ryan Giggs – 8.5
Probably the peak season of Giggs' playing career. Who can forget his run and goal against Arsenal?
Andy Cole – 8
Already one of the best strikers in the country, benefited hugely from the arrival of Dwight Yorke and scored 24 goals in all competitions.
The myth of Paul Scholes outweighs the reality but he was good, as was Ryan Giggs
Dwight Yorke – 8.5
Joined from Aston Villa as a £12.6m record arrival and linked up beautifully with Cole. His 29 goals were imperative to the Treble.
Subs: David May, Nicky Butt, Teddy Sheringham, Phil Neville, Jesper Blomqvist, Ole Gunnar Solskjaer and Raimond van der Gouw - 8.5
United's 1998-99 season was really defined by their substitutes, like Ole Gunnar Solskjaer's run of dramatic late goals and Teddy Sheringham's role. Add in the quality of Phil Neville and Nicky Butt and these are some fine players to have in reserve.
Manager - Alex Ferguson - 9.5
This was the peak of his career as a manager, the
