LOS ANGELES - Manny Pacquiao says the pieces were falling into place for a world title fight with Floyd Mayweather until the American boxer tried to low-ball him on the split of the pay-per-view revenue.

Pacquiao said he called Mayweather personally to try to broker a deal for a world championship fight and thought they had an agreement until Mayweather brought up the pay-per-view.

Mayweather said he would give Pacquiao a $40-million lump-sum payment if Pacquiao agreed to let him keep the pay-per- view earnings for himself.

"It was embarrassing to me. He was trying to take advantage of me. It is clear he didn't want to fight."

Some experts have estimated that the pay-per-view could be around $160-million. Pacquiao and Mayweather have tried several times to get a contract signed but it has been scuttled for a variety of reasons, including disagreements over blood testing and the share of the purse.

"I called Floyd and told him that we need to make this fight happen," Pacquiao said at The Beverly Hills Hotel. "I said he could have whatever he wants, blood testing, 50/50 split ... and he said 'Oh, well. I will give you what you want.' Then he mentioned the pay-per-view."

For now, Pacquiao and the unbeaten Mayweather have lined up other opponents with speculation that the mega-fight could happen later in the year.

Pacquiao is scheduled to face American Timothy Bradley on June 9 at the MGM Grand Hotel and Casino in Las Vegas for Pacman's WBO Welterweight belt.

Mayweather is set to fight Puerto Rico's Miguel Cotto on May 5 for Cotto's World Boxing Association super welterweight title at the same venue.

Pacquiao's trainer Freddie Roach said they are not taking Bradley lightly but it is hard not to get excited about a possible upcoming mega-fight against Mayweather.
