(Top Rank) Retired boxing star Floyd Mayweather Jr. bared that Manny Pacquiao was the best boxer he ever faced in more than two decades of his flawless career. Out of the 50 unbeaten bouts since 1996, Mayweather said Pacquiao, the only eight-division world boxing champion, had stood out the most when they met in May 2015. “The best fighter I’ve ever fought probably was Manny Pacquiao. It’s because of his movement. He’s a hell of a fighter,” said Mayweather in his guesting at The Million Dollaz Worth of Game podcast.
