Floyd Mayweather and Manny Pacquiao: not even in top three in Welterweight

Former light-welterweight and welterweight world champion Paulie Malignaggi has claimed that Floyd Mayweather and Manny Pacquiao are not even in the top three of the best welterweights in the world, inferior to British pair Amir Khan and Kell Brook plus American Keith Thurman.WBA and WBC welterweight champion Mayweather faces WBO title holder Pacquiao in Las Vegas on 2 May in one of the most most anticipated boxing bouts in history.

It will also be the richest fight in the history of the sport, with at least $300m to be split between the pair, 60/40 in Mayweather's favour. Malignaggi, however, argues that while Mayweather, 38, and Pacquiao, 36, are the "biggest names", they are not the best fighters.

Malignaggi, 34, lost to Khan back in 2010.. Khan, meanwhile, has been linked with a domestic battle against IBF champion Brook."

Here's the thing: I think Brook, Khan and Thurman are the best welterweights in the world right now," Malignaggi told behindthegloves.com"Mayweather and Pacquiao are the biggest names but I think here we are in 2015, Kell Brook, Keith Thurman and Amir Khan are the best three welterweights in the world and because they are the best three welterweights in the world, you're not going to see them against each other right away.
