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.

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.”
