More boxers are expressing their belief that Floyd Mayweather is not the unbeatable pugilist that the pound-for-pound king claims to be.
The latest to share his opinion is eight-division title holder Manny Pacquiao whose chance of a match with Money May appears dimmer amid reports that the Filipino congressman has renewed his contract with Bob Arum's Top Rank Promotion.
The southpaw legislator said on Thursday that his former stablemate, Amir Khan, stands a chance of defeating Mayweather because of the British boxer's speed.
But the chance of Khan winning over Mayweather is dependent on the quality of his training, Pacquiao told Boxing Scene, and also on the unbeaten boxer being confirmed by Money May over Marcos Maidana of Argentina who won in an online popularity poll to pick Mayweather's opponent on May 3.
Manny knows Khan quite well since the two were sparring partners under Freddie Roach, but Khan left in 2013.
Besides Pacquiao, who is scheduled for a rematch with Timothy Bradley on April 12, undefeated super middleweight champion Andre Ward also spoke highly of Khan whose speed he also noted.
"He has an awkward style, and he hits a lot harder than people think, at least from what I've seen," Boxing Scene quoted Ward.
"The awkwardness, the speed and the pop he has - I think he can give anybody trouble on any given night," Ward said.
However, there are boxers who have a different opinion such as lightweight champion Lydell Rhodes.
Mayweather had previously admitted avoiding Pacquiao as an opponent for fear of losing his undefeated status before he hangs up his boxing gloves.
