Eight division world champion Manny Pacquiao (57-6-2, 38KOs) is willing to postpone his planned retirement - if he gets a rematch with Floyd Mayweather Jr. (49-0, 26KOs).

After six years of failed negotiations, they finally collided on May 2nd with Mayweather winning a twelve round unanimous decision. The fight generated record numbers and a smashing 4.6 million pay-per-view buys.

The fight itself was lacking the expected fireworks. After the fight, Pacquiao revealed that he suffered a right shoulder injury in training camp and then further hurt himself in the fourth round of the fight. He had surgery a few days later and has been on the shelf ever since. The shoulder is 100% healed says Pacquiao.

Mayweather retired on September 12th after beating Andre Berto over twelve rounds. Pacquiao also planned to retire, following his upcoming trilogy fight with Timothy Bradley on April 9th, but he wants to hold out with the hope of Mayweather coming out of retirement to fight him again.

That could be a long wait with Mayweather stating that he doesn't have any interest in facing Pacquiao again. Even with Mayweather brushing off the Filipino star's advancements, Pacquiao is still very focused on luring him back to a second fight.

Some still believe Mayweather will return to the ring for at least his 50th fight. If that happens he has a lot of options to choose from, but Pacquiao is obviously the most lucrative from a financial standpoint. It wouldn't be nearly as big as the first fight, but even if the fight had half the success it would be the biggest financial option for both.

"I have been very vocal about it (fighting Mayweather) even before the Bradley fight was made official on New Year's eve," Pacquiao explained to Philboxing.com. "The reason is simple, I want to end my 21-year boxing career with a big bang so to speak."

"And what would be the biggest fight to end a career than fighting the best and finest boxer at least in this era? We could have given that last May when we faced each other but due to unavoidable circumstances, sports fans failed to get the results they wanted. Not that Floyd's legacy and mine can still be questioned but wouldn't it be more colorful and meaningful closing our respective careers on higher notes at the same time putting an end, too, on the business we started but we were unable to finish?"
