The most awaited fight between Manny Pacquiao and Floyd Mayweather Jr. may happen next year and the better news is it could happen twice in 2015.

Top Rank CEO Bob Arum said he is already convinced that the two biggest names in boxing will finally face each other inside the ring.

According to Daily Mail, Arum is confident that they will fight for the first time then schedule a rematch on the same year. After decades of expecting, the fans will finally be able to witness a fight that will mark history in the boxing industry.

The fight, which is reportedly scheduled in May, is believed to be worth $300 million, the priciest in the history of the sport and the rematch, expected to happen in September 2015 is estimated to earn more than half a billion dollars.

The pay-per view channels of the two champs, HBO for Pacquiao and Showtime for Mayweather, have reportedly agreed to share the earnings in the match.

"Both networks want this to happen. All signs seem to point to a first fight early next year," Arum was quoted by Daily Mail as saying.

He also claimed that there is the possibility of being able to negotiate the two fights. "A second fight in the autumn would provide a different cash split because the winner of the first would claim the higher percentage. As each of them believes he would win, that provides an extra incentive."

The Filipino boxer has also reportedly agreed to submit himself for drug testing after Mayweather demanded him to do so. Now, all that's left to do is for the undefeated American fighter to agree to fight Pacquiao.

In an article, Fight Saga discussed some of the reasons why Mayweather has not agreed to clash with Pacquiao noting that that he is "a bit too pre-occupied with the prospect of losing." The report has quoted Pacquiao as saying, "[He is] not [scared] of fighting, but perhaps of what one night could do to his zero of losses."

Fight Saga said Pacquiao could have a point as athletes really become scared of coming up short in any competition.

"... I think he is worried about his record. He talks about his zero losses. The zero that means so much to him means nothing when measured against who he fought. You talk pound-for-pound best, or undefeated champion. If you don't defend against the best, none of that means anything," Pacquiao added.

Fight Saga said that if Mayweather refuses this perfect chance (which could also be the last one considering Pacquiao's nearing retirement) then people would always know him as the boxer with the perfect record who never fought Pacquiao.
