Top Rank's CEO Bob Arum believes a fight between Manny Pacquiao and Floyd Mayweather Jr. is possible for 2015, because the networks, HBO and Showtime, are discussing the idea of working together - like their did in 2002 with Lennox Lewis-Mike Tyson - to stage a joint Mayweather-Pacquiao pay-per-view event.

According to Arum, CBS Corporation president and CEO Leslie Moonves is brokering the deal. CBS is the parent company of Showtime, which has a six-fight deal with Mayweather. Pacquiao is under contract to HBO, and returns to action this Saturday night in Macau in a title defense against Chris Algieri.



"The networks are now already talking," said Arum to GMA News. "I am now more optimistic that the fight is going to happen than I was three or four years ago. I am talking to responsible people who are in touch with the Mayweather guys. All of these people have the ability to move it ahead and make it happen."

"If it happens, we're considering the Cowboys Stadium. It is the only venue which has the capacity to host a big show such as the Pacquiao-Mayweather fight.

"Still, it depends if Manny wins the fight. All I can say is that now, there's a ray of sunshine that it would be possible."
