Floyd Mayweather 'Named Greatest Boxer Ever' By BoxRec With Muhammad Ali Fourth

The American welterweight won all 50 of his professional fights over a 21-year career, and he reminded the world about it.

The 44-year-old amassed 2256 points according to the system, a long way clear of second-placed Pacquiao on 1629.

Mayweather memorably fought against Conor McGregor in August 2017, when he won his 50th professional bout, and recently took on American YouTube personality Logan Paul in an exhibition match.

He beat rival Pacquiao in 2015 in a long-awaited clash between the two men considered to be the best pound-for-pound fighters in the world at the time.

Argentine middleweight Carlos Monzon comes in third on the list on 1588 points before Ali on 1485.

Bernard Hopkins (1470) is fifth ahead of Sugar Ray Robinson (1469), Joe Louis (1466) and Archie Moore (1289).

Oscar De La Hoya comes in ninth (1262) and Julio Cesar Chavez (1202) rounds out the top 10.

Joe Calzaghe is the highest-ranked Brit on the list - coming in 32nd placed on 859 points.
