Floyd Mayweather's decision to fight Andre Burto in what is likely his finale bout this September was criticized by those who feel the veteran still has something to prove before he can be considered amongst the sport's best.
Mayweather himself though, never one to be short on confidence, is already convinced he has outshone every fighter who has gone before him.
Appearing on ESPN's Spanish language Deportes show, the controversial figure was asked to rank the top five boxers in the history of the sport. Unsurprisingly Mayweather put his name first, but fighting fans may be shocked to see where Muhammad Ali, many people's 'greatest ever', appeared on the list.

Mayweather reeled off a number of reasons why he deserved to be number one, including number of champions defeated and money brought in, and made some good points along the way.
It was the undefeated champion's picks for the remaining spots that are likely to cause much of the debate, however.
Whether searching for controversy or simply playing the pantomime villain, Mayweather relegated Muhammad Ali to just number five on the list behind Roberto Duran, Pernell Whitaker, and Julio Cesar Chavez.
Citing Ali's surprise defeat to Leon Spinks, as well as the fast-talking fighter's failure to win a title at different weights, Floyd Mayweather seemed convinced about his decision.
Many boxing fans didn't share that view:
Considering Mike Tyson's emotional speech when inducting Muhammad Ali into the Boxing Hall of Fame this past week - the former eulogizing about his mentor's talents - we are pretty sure Floyd Mayweather might be getting a call from Iron Mike to question his thought process too.
