Golden Boy Promotions President Oscar De La Hoya has serious doubts about the possibility of a deal being reached for a 2015 mega-match between Floyd Mayweather Jr. and Manny Pacquiao.

Top Rank's CEO Bob Arum, who promotes Pacquiao, is trying to get a deal together with CBS CEO Les Moonves. CBS is the parent company of Showtime, who have Mayweather under an exclusive deal.

De La Hoya's company had tried for years to make that fight. Back in 2010, a deal was practically agreed upon, but then Pacquiao rejected Mayweather's demand for a random drug testing protocol.

But now, to make the fight happen next year - Pacquiao is willing to yield on all matters, with Mayweather getting the edge in money, pay-per-view revenue, random drug testing and top billing.

“I’ll believe it when I see it,” De La Hoya said. “I’ve heard it for about five years. It’s very complicated. First of all, you have one fighter [Pacquiao] with HBO and the other with Showtime. You have sponsors. But most importantly, you have egos and egos can get in the way of making big fights happen.”
