If Floyd Mayweather Jr., a five division champion, is able to retire with an undefeated record - Manny Pacquiao's trainer, Freddie Roach, says his boxer should absolutely be considered as the better fighter in the record books - despite Pacquiao, an eight division world champion, getting knocked out three times in his career.

"This fight coming up [with Marcos Maidana]. He's just going to move with this guy. He's facing a dangerous puncher, he's not going to stand with him. It's all defense, it's f***ing boring. He's great at what he does, I'll give him that, but he's boring."

"It think its about putting a show on and giving the people what they want. Putting people to sleep is not a good thing. It's the way he fights. I'm not going to fault him for it. He's very good at what he does, but he's boring. Andre Ward is a great fighter, but he's a little bit boring also. "

While Roach considers Pacquiao to be a far more exciting fighter, and a better fighter, it is Mayweather who occupies the top two positions for record pay-per-view figures - 2.4 million for Oscar De La Hoya in 2007 and 2.2 million for Saul Alvarez in 2013.

While Pacquiao has never come close to reaching those type of pay-per-view stats for a single event - Roach believes he was certainly capable of doing so if he didn't become compassionate. Pacquiao has not scored a knockout since his 2009 TKO win over Miguel Cotto.

"If Manny didn't stop knocking people out, he would have stayed up there with Mayweather [with the pay-per-view buys]. But when he became compassionate, a lot of people didn't buy the fights," Roach said.

Very few believe a Mayweather-Pacquiao fight will ever happen, with both sides unable to reach an agreement for at least the last four years.
