Manny Pacquiao recently announced his intention to fight Floyd Mayweather Jr. for charity, stressing money is not the reason he wants to take on boxing's No. 1 superstar. 

Pacquiao, 35, admitted that he has two more years left before he finally closes out his epic boxing career. Apparently, Pacman wants to end his career on high note, and there's no bigger fighter out there than the reigning pound-for-pound champion—Money May.

In a recent interview with Aquiles Zonio of the Philippine Inquirer, the eight-division world champion challenged Mayweather anew for a showdown with all the prize money and revenues from pay-per-view buys and merchandise sales donated to charity.

"I'm not desperate to fight him just for the sake of money or material things. I'm not the one seeking this fight; rather it's the boxing fans all over the world," Pacquiao said in the interview.

"I am ready to submit myself to any kind of stringent drug testing. Above all, I challenge him to include in our fight contract that both of us will not receive anything out of this fight," Pacquiao challenged. "We will donate all the proceeds from the fight-guaranteed prize, should there be any, gate receipts, pay-per-view and endorsements-to charities around the world."

Pacquiao said his legal representatives are already settling his tax problems both in the Philippines and the United States, assuring that he will pay all the discrepancies he might have incurred.

"As to my tax problem, my lawyers are fixing it already," Pacquiao told Zonio. "I'm paying my taxes religiously. It is just a matter of reconciling our records with the tax agencies both here and abroad. Should there be any discrepancy, rest assured, I will settle it. I'm a lawmaker and I'm a law-abiding citizen."

Fight Like a Man

Pacquiao, who has been a victim of Mayweather's trash-talking assaults on Twitter, apparently has had enough of the Grand Rapids native's antics, daring him to arrange their showdown—if he's a "real man."

"Floyd, if you're a real man, fight me," Pacquiao said. "Let's do it for the love of boxing and for the fans. Let's do it not for the sake of money. Let's make the boxing fans happy."

Pacquiao has yet to pick his next opponent for his April 12 fight, but his latest comment indicates his strong desire to take on Mayweather in a fight that will determine the best boxer of this era. Many boxing analysts and followers assert Pacquiao wants to have a legacy slugfest with Money May to settle their score once and for all.
