Manny Pacquiao and Juan Manuel Marquez have a history that speaks for itself. While the potential greatness of a bout between Pacquiao and Floyd Mayweather Jr. is a popular topic of discussion in boxing circles, the rivalry between Pacquiao and Marquez is actually great. There are no hypotheticals involved. When these two fought, all four times, the end result was memorable. Were the second and third matches as memorable as the first and fourth? Probably not. But they were still pretty amazing.

Pacquiao is currently coming off a big victory over Brandon Rios. Marquez is fresh off a tough loss to Timothy Bradley. According to Fight News, Top Rank boss Bob Arum is looking to pit one against the other for what would be the fifth, and presumably final, chapter of their rivalry.

Marquez has repeatedly stated that he is not interested in a fifth match against Pacquiao. He believes that his knockout win in the fourth bout definitively answered who the better man was, and he doesn’t want to risk tarnishing that memory.

Arum acknowledges Marquez’s reluctuance, but apparently he’s prepared to make the 40-year-old a pretty sweet offer. Per Fight News, Marquez stands to make between $13 and 15 millions should he agree to a fifth showdown against Pacquiao.

If Marquez doesn’t agree to fight Pacquiao again, he will be left without a dance partner. The person he wants a rematch against, Bradley, will likely be Pacquiao’s backup option should talks with Marquez fall apart. And since fighting Pacquiao again will make Bradley more money than fighting Marquez again, that’s probably the direction he’ll lean in.

Essentially, Marquez can take the biggest pay day of his career and fight Pacquiao, or he can turn the fight down and fight a no-namer next April or May.
