May 11 is a day that has contrasting FA Cup final fortunes for each side of the Manchester divide.
While for United it was a day to celebrate in 1996 after Alex Ferguson's men defeated the old enemy Liverpool, for City it was one to forget in 2013 as Wigan Athletic pulled off a huge shock.
Arsenal remember the date fondly as they were crowned champions of England 19 years to the day, while just 12 months ago Saracens were standing tall in Europe in what was a familiar story.
Below we take a look at some of the memorable sporting moments from May 11.
1991 – Golden Graham's Gunners lift league title
For the second time in the space of three seasons, Arsenal were crowned champions of England in the 1990-91 campaign.
Some 13 years before Arsene Wenger's 'Invincibles', George Graham's team lost just once and thumped Coventry City 6-1 in their final game of the season in a hectic campaign.
During the season, Tony Adams was jailed for drink-driving and the Gunners were docked two points for their part in a brawl at Manchester United in October 1990.
1996 – Cantona sinks the 'Spice Boys'
There is little love lost in the rivalry between Manchester United and Liverpool but in truth the 1996 FA Cup final was a forgettable game.
Eric Cantona settled the clash at Wembley, shooting through a crowd of players in the 85th minute to complete a league and cup double for the Red Devils.
While the action on the pitch did not live long in the memory, the sight of Liverpool's squad arriving in white Armani suits has lasted the test of time.
The funky attire did little to shelve the 'Spice Boys' moniker that had been given to the Liverpool squad by the British press.
2013 – Watson header sees Latics shock City
Seventeen years later and the blue half of Manchester suffered an upset FA Cup final defeat as City were downed 1-0 by Wigan Athletic.
City's expensively assembled cast were the overwhelming favourites having won the same trophy two years previously and been crowned Premier League champions in 2011-12.
But substitute Ben Watson headed home in the first minute of injury time to leave City – who had Pablo Zabaleta sent off six minutes from the end – little time to muster a response.
Just a couple of days later, City sacked boss Roberto Mancini.
2019 – Sarries reign in Europe again
The past few months have been particularly trying for Saracens, who will be relegated from the Premiership over a breach of salary-cap regulations.
But just 12 months ago, Sarries were celebrating a third European Rugby Champions Cup success in the space of four years thanks for a 20-10 triumph over Leinster.
