Man United were crowned Premier League champions 20 years ago on May 16

What a difference 20 years make. Boyzone were No 1, the Labour Party were in power and the film Notting Hill had just come out.

Fast-forward to the present day and Stormzy is No 1, the Conservatives run UK Government and everyone is watching the blockbuster End Game.

However, in that time-frame one thing still remains the same - Manchester rules the Premier League roost.

While Manchester City are basking in a second-successive title, Thursday marks the 20th anniversary since their bitter rivals Manchester United held aloft the trophy to conclude a dramatic 1998-99 league campaign on their way to an unprecedented Treble.

Just like their 'noisy neighbours' United (79 points) were crowned champions of England by a single point on the final day, pipping Arsenal (78 points).

Goals from David Beckham and Andrew Cole saw Sir Alex Ferguson's side come from behind to win 2-1 against Tottenham at Old Trafford.

Chelsea finished third that season on 75 points - just four behind United and three behind Arsenal.

Twenty years on and the trio were all tussling for position in the Premier League... but this time it was for a top-four place - something only Chelsea secured with a third-place finish.

That's not the only obvious difference between then and now though.

For starters, only half of the Premier League teams remain in the top-flight. Leeds United, Aston Villa, Derby County, Middlesbrough, Sheffield Wednesday, Coventry City, Wimbledon, Charlton Athletic, Blackburn Rovers, Nottingham Forest all currently ply their trade in the second tier or below.

Wimbledon have even changed their identity becoming MK Dons and moving to Milton Keynes, with the rise of AFC Wimbledon as a phoenix club now in League One.

Delving further of those remaining 10 clubs; West Ham United, Leicester City, Newcastle United and Southampton have all suffered relegation in that time-span meaning only Manchester United, Arsenal, Chelsea, Liverpool, Tottenham and Everton have always beaten the drop.

To the eagle eyes among you, you would notice that there is no Manchester City mentioned in above list of 20 teams in the 1998-99 season. That was because they were in the third tier and about to inflict heartache on Gillingham in a dramatic Second Division play-off final.

While City are one of four teams who can look forward to Champions League football next season, possibly five if Arsenal win the Europa League on May 29, during the 1998-99 term there were only three spots available. United and Arsenal qualified automatically for it, while Chelsea entered the third qualifying round.

Leeds, who suffered Championship semi-final play-off heartache against Derby on Wednesday, finished fourth that season - earning them an automatic spot in the UEFA Cup first round.

Tottenham, who finished 11th, and Newcastle, who finished 13th, were the other qualifiers for the UEFA Cup first round following their League Cup success and FA Cup runners-up finish respectively.

It should be noted that the UEFA Cup is now the Europa League after rebranding - 20 years ago there was no group stage.

West Ham finished fifth that season and therefore qualified for the UEFA Intertoto Cup third round - a now defunct competition.

Michael Owen (Liverpool), Jimmy Floyd Hasselbaink (Leeds United) and Dwight Yorke (Manchester United) shared the Golden Boot that season with 18 goals apiece and 20 years on there was another three-way tie for the Premier League's top goalscorer. This season Liverpool duo Mo Salah and Sadio Mane matched Arsenal striker Pierre Emerick-Aubameyang in scoring 22 goals.

Aside from the format of the competition, the money in football has vastly changed. The world-record signing at the time was Denilson following his £21.5million move from Sao Paulo to Real Betis in 1998. The British transfer record was still Alan Shearer's £15m switch from Blackburn to Newcastle in 1996. Today, the most expensive transfer in history is his Brazilian compatriot Neymar's £198m deal from Barcelona to Paris Saint-Germain in 2017. The current British transfer record is the £89m Manchester United paid to re-sign Paul Pogba from Juventus in 2016.

In terms of annual wage, a Premier League footballer would earn £313,959-a-year in 1998-99 - according to Sporting Intelligence. Compared that to the modern day footballer and Alexis Sanchez currently earns £500,000-a-week at Manchester United (inclusive of bonuses).

While Sanchez's struggles on-the-pitch are indicative of United's issues at present at least they can reflect on former glories of the past - namely the first piece of the Treble being won on this day 20 years ago.
