Sportsmail's Jeff Powell names his Top 10 boxers of all time as Floyd Mayweather calls time on his career following his 49th and final victory against Andre Berto in Las Vegas

1) Sugar Ray Robinson 1940-65

I watched Robinson when, as a boy, my father smuggled me into Earls Court for his fight against Randolph Turpin. Robinson lost but I was in awe at the time and the more I saw of him the more I appreciated his all-round supremacy.

2) Muhammad Ali 1960-81

Truly The Greatest in how he transcended boxing and became the most recognisable face on the planet. The best heavyweight I have seen live.

3) Sugar Ray Leonard 1977-97

The diamond in a quartet who glittered through boxing’s golden age.

Powerful and intimidating. Still believes to this day he won his epic fight with Leonard.

Detroit hitman who engaged in historic wars with Leonard and Hagler.

9) Larry Holmes

Suffered for years from lack of recognition because he was Ali’s sparring partner. Yet he has an outstanding and long-running world heavyweight champion in his own right.

10) Joe Frazier

'Smokin’ Joe defeated Ali in the Fight of the (previous) Century in New York’s fabled Madison Square Garden. Ali won the re-match but then these two great heavyweights fought each other almost to death when they completed their epic trilogy in the Thrilla in Manilla.
