Floyd Mayweather and Manny Pacquiao's long-awaited bout took place five years ago but failed to meet expectations.
Massive sporting events do not always live up the occasion.
The boxing world was delivered a reminder of that five years ago as a fight a long time in the making proved a drab affair.
It is the unexpected that often produces the most excitement and that was the case during a 2015-16 Premier League campaign that stands as arguably the most memorable in the division's history.
Here we look back at May 2 in the world of sport.
2009: Pacquiao makes light work of Hatton
"From the ends of the earth to the centre of the ring" was the tagline attached to a light-welterweight title bout billed as the' Battle of East and West'.
With seven seconds left in the second round, Ricky Hatton was indeed in the centre of the ring, on his back having been dumped to the canvas by a thunderous left to the chin from Manny Pacquiao.
The fight marked the last at elite level for Hatton, who finished his career in 2012 with a loss to Vyacheslav Senchenko.
Pacquiao has gone on to secure his legacy as one of the greatest boxers of all time, but his journey has not been without its lows, the biggest of which would come six years later at the same MGM Grand Garden Arena venue...
2009: Leinster-Munster semi-final draws record crowd
Leinster v Munster is regarded as one of the biggest provincial rivalries in world rugby, and it reached new heights as the pair met in the Heineken Cup semi-finals at Croke Park.
A crowd of 82,208, a world-record attendance for a club match, witnessed Leinster secure their place in the final with a 25-6 victory.
They would go on to lift the trophy, beating Leicester Tigers 19-16 at Murrayfield.
2012: Messi breaks European club goals record
Lionel Messi's incredible career has been defined by him shattering records and collecting medals at will.
Eight years ago he bettered a mark that had stood since the 1972-73 season with a hat-trick against Malaga.
The treble took Messi to 68 goals for the 2011-12 season, the most by a single player in a European club season.
Gerd Muller had previously held the record with 67. Messi would go on to stretch his advantage over the Germany great, finishing the campaign with a remarkable 73 goals.
2015: 'Fight of the century' fails to inspire
After years of protracted and tempestuous negotiations, Pacquiao and Floyd Mayweather finally agreed to touch gloves in the biggest fight of the 21st century.
The contest did not match the hype surrounding it, however, Mayweather maintaining his unbeaten record in uninspiring fashion.
Pacquiao struggled to land punches on a defensive Mayweather, whose tactical acumen won the day in a fight some dubbed 'Better never than late' in the aftermath.
Mayweather followed up that win with a victory over Andre Berto in September, before coming out of retirement in 2017 to defeat UFC star Conor McGregor and improve to 50-0.
2016: Leicester achieve the impossible
The established order of the Premier League was upset in unbelievable fashion in 2015-16 as 5,000-1 outsiders Leicester City, having narrowly avoided relegation the previous season, clinched the title.
Tottenham had been the Foxes' closest challengers in a year where Manchester City, Manchester United and Arsenal all struggled for consistency, with Liverpool and Chelsea well off the pace.
However, it was Chelsea who ended Tottenham's hopes and ensured the trophy would head to the King Power Stadium.
Spurs needed to win at Stamford Bridge to keep their hopes alive and led 2-0 thanks to goals from Harry Kane and Son Heung-min.
But Gary Cahill pulled one back and Eden Hazard levelled matters seven minutes from time to spark delirious scenes among the Leicester players watching on TV.
