Manny Pacquiao's outspoken strength and conditioning coach Alex Ariza has taken the gloves off and ripped into promoter Bob Arum for not making a fight between Pacquiao and Floyd Mayweather Jr.

In an interview with Fighthype's Ben Thompson, Ariza didn't mince words, and said he really believes Maweather wants to make the fight, and that it's Arum standing in the way.

"It's always about what's best for Bob and his agenda. ... I know that Michael Koncz says that he's having a meeting with Bob to negotiate the Mayweather fight. They're having a meeting on how to make sure this fight doesn't happen. That's what their meeting is about. ... Bob Arum is a greedy pig. ... Arum hates Floyd Mayweather, can't stand him, doesn't want to see him make a dollar, can't stand Golden Boy, doesn't want to do business with them. But instead of doing what's best for the sport, what's best for the fans, and what's best for the fighters because they'll get the payday of a lifetime, no, it's all about him. ... Unless you can tell me and convince me otherwise, because I'm thoroughly convinced and believe Floyd really does want to have this fight."

Now this is all quite a statement, to say the least. Read the full interview, because there's so much more fire in there, including that he hears Arum is trying to get Ariza and Freddie Roach away from Julio Cesar Chavez Jr.

Maybe Ariza has overstepped his bounds here, but the gist is that he feels Arum oversteps his on a regular basis. Fight fire with fire, I guess. This whole saga is heating up like never before, and Bob Arum is taking the brunt of the criticism from just about all sides. How will he respond?
