Floyd Mayweather Jr. has explained, in further detail, why he refuses to give Manny Pacquiao an even 50-50 revenue split to finalize the biggest fight in the sport of boxing. Mayweather, who appeared for a live interview on "Costas Tonight," discussed his reasons for not agreeing to a 50-50 split with Pacquiao. Mayweather also detailed why he offered Pacquiao a flat guarantee of $40 million dollars - with 0% of the pay-per-view revenue. Mayweather also refuses to accept Pacquiao's counter-offer, which is a 45-45 split with the winner receiving the remaining 10%.

"I got on the phone directly with Manny. I done my homework and saw what he was making for big fights. The offer that I made him, I offered him $40 million and told him that I would wire him $20 [million] in 72 hours. The manager said that he would get back to me, a guy by the name of Michael Koncz flew to Las Vegas to talk to me because he said that he was in control. I met with him a couple of times and tried to make the fight and then they said they were going another route," Mayweather said.

"How my deal is structured at this particular time in the sport of boxing, I keep 100% of the [pay-per-view] revenue, so why would I even give a guy 50-50. At this particular time, I'm not just the highest paid guy in the sport of boxing, I'm the highest paid athlete.  Everybody is entitled to their own opinion, but I come first...self preservation. I put myself first and worry about my family. If the fight happens it do. Do I want it to happen? Absolutely! If it don't, so be it. Because when my career is over, I can't come to Bob [Arum] and say 'I need you to pay my bills.'"

"I'm not giving up the split. I'm not. I can't. I can't afford to. No I'm not. I gave this sport my whole life. I've been dominating in this sport. I have record breaking numbers that I've done. He has no record breaking numbers. With or without Pacquiao, Floyd Mayweather is okay. Floyd Mayweather fights for Floyd Mayweather. At the end of the day, Floyd Mayweather has to be happy."
