Throughout his 21 years as a professional boxer, Mayweather has faced some stellar names from Ricky Hatton, to Oscar De La Hoya and Saul "Canelo" Alvarez, but when it comes to the best he's faced, his answer may not surprise fans. 

"The best fighter I ever fought probably was Manny Pacquiao," Mayweather told Millon Dollaz Worth of Game. 

"It’s because of his movement. He’s a hell of a fighter and I can see why he won so many fights and I can see why he’s going down as a Hall of Famer. It’s just certain moves he makes.”

Mayweather and Pacquiao met in 2015 and it was a fight which broke numerous records such as pay-per-view sales and fighter purses. 

However, while there was plenty of hype going into the contest, it was a fight which failed to live up to expectations with Mayweather once again showing his class and comfortably getting the win on the judges' scorecards.
