Undefeated American boxer Floyd Mayweather Jr is still not interested in fighting Filipino boxing champ Manny Pacquiao despite the eight-division titleholder's convincing defeat of American pugilist Timothy Bradley on April 12.

He believes that Pacman is only willing to push through with the so-called Dream Match because of his tax problems with the Philippine government. Money May disclosed to Boxing News 24, before he fought Argentinean boxer Marcos Maidana on May 3 that Pacquiao is to blame for his financial woes because the southpaw refused to accept his two conditions for their proposed bouts in 2010 and 2012.

Mayweather, who has earned about $400 million in his fights, claimed he offered Pacquiao a guaranteed purse of $50 million in 2010 and $40 million in 2012, but Pacquiao was not willing to accept his conditions for random blood testing and random urine testing.

In his last bout, Pacquiao was guaranteed a $20 million purse, plus pay-per-view revenue, but Top Rank Chief Executive Bob Arum disclosed on Monday that PPV income for the April 12 rematch generated only between 750,000 and 800,000 PPVs, while the Philippine taxman insists that Pacquiao has tax arrears of P2.2 billion or about $50 million.

Boxing News 2014: Would Floyd Mayweather Heed Muhammad Ali's Challenge for Money May to Fight Manny Pacquiao Next?

Pacquiao refused because of his belief that extracting blood from him before a ring match would weaken his body and could cause him to lose.

Money May said, "I don't need him, he needs me. Now he's begging - 'Do it for the fans." I fight my fights for Floyd Mayweather."

No less than former world heavyweight champion and boxing icon Muhammad Ali had challenged Mayweather to fight Pacquiao, but Money May has a number of reasons, including Pacquiao being under Top Rank.

However, such kind of statement appears to confirm what many boxing observers say that Mayweather is actually scared of boxers who are stronger than him that's why he picks only opponents whom he could easily beat.

Bill Phance of Eastsideboxing, for instance, commented that he finds it strange that Floyd Mayweather Sr said that his son could easily beat Pacquiao when "he couldn't even beat Maidana convincingly."

He noted that Money May, "for the first time in his career, looked his age, and didn't seem to be the same guy that had dominated Robert Guerrero and Saul 'Canelo' Alvarez recently."

Mayweather is 37, Pacquiao is 35 and Maidana is 30.

Phance concluded that if a B-grade boxer like Maidana, who has teasingly called Mayweather a "baby girl," gave Money May huge problems and almost won, "then it seems only obvious that Pacquiao would beat him if that fight were to be made."

He added that Maidana created the blueprint how to beat Mayweather, and Pacquiao, by following the blueprint to the letter, would break the 46-0 record of Money May.
