10. Floyd Mayweather Jr.
Despite a professional record reading 50 fights and 50 wins, and ESPN, BoxRec and The Ring ranking 'Money' as the greatest ever pound-for-pound boxer, Mayweather somehow is voted in at number 10 on this fans poll. Don't worry, we are as shocked as you are!
9. Oscar De La Hoya
'The Golden Boy' ranks one place higher than Mayweather, despite Floyd coming out the victor via a split decision when the pair met in 2007.
8. Julio César Chávez
The Mexican lost just six times in a 115-fight career, ultimately hanging up the gloves in 2005. His sons Omar Chávez and Julio César Chávez Jr are also professional boxers, with Omar currently the WBC Youth Intercontinental welterweight champion whilst Jr is a former WBC middleweight champ.
7. Henry Armstrong
Standing only at five feet and five-and-a-half inches tall, 'Homicide Hank' was named as the second-best fighter in the last 80 years by The Ring, whilst ESPN ranked him as the third greatest fighter in the sport's history.
6. Pernell Whitaker
A southpaw fighter, 'Sweet Pea' won 40 of his 46 fights, with 17 coming by way of knockout. Whitaker sadly passed away last year aged 55.
5. Roberto Durán
Durán's remarkable career spanned a mammoth five decades as he followed Jack Johnson to become just the second boxer to achieve the feat. Hailing from Panama, Manos de Piedra was a four-weight world champion.
4. Thomas Hearns
One of the taller fighters on this list at six feet and two inches, 'The Hitman' won 61 of his 67 fights.
3. Manny Pacquiao
'PacMan' is boxing's only ever Octuple champion as he held world titles in eight different weight classes. He was beaten via a unanimous decision when he fought Mayweather in Las Vegas, before becoming a leading figure in Filipino politics.
2. Sugar Ray Leonard
The man who Mayweather initially complained about being ranked above him, Leonard was famously part of the 1980s 'Fabulous Four' alongside Roberto Durán, Thomas Hearns and Marvin Hagler. He lost just three times in 40 fights.
1. Sugar Ray Robinson
Winning 173 times in a 200-fight career, 109 times by way of knockout, Sugar Ray Robinson takes the top spot on the fans' vote. From 1943 to 1951, the American set history as he went on a 91-fight unbeaten run and is commonly referred to as the greatest of all time.
