Leave it to Bob Arum to mince no words when talking about anything boxing. The Top Rank Promotions head said that both Manny Pacquiao and Floyd Mayweather Jr. have to agree to fight each other because they owe it to the sport to make the biggest fight in history.

"It's stupid if the fight doesn't happen," declared the affable and vibrant 82-year-old promoter to USA Today on Tuesday night.

“What, is Mayweather going to fight Amir Khan? Who gives a (expletive)? We've announced we're willing to make anything happen. Now somebody has got to contact us so we can sit down and explore how it can happen. Isn't that the way normal people deal? You can't wave a wand. I've said unequivocally, we're ready to sit down and see if a deal can be reached.” Arum also added in the same interview.

The Pacquiao-Mayweather bout has been discussed countless times before hitting its peak at the prime of Pacquiao’s career around 2011. The Filipino has a record of 55 wins (38 knockouts) against 5 losses and 2 draws while the American is undefeated in 45 matches with 26 KOs.

While there is still no formal agreement between the top boxers in the world, sportsbooks have already sent feelers on what the betting lines will look like if Pacquiao-Mayweather does happen. Floyd is the hands down favorite in all with -140 to -130 betting odds across his name, while Pacquiao is the under at around +125 to +135 in most books.

Also in the interview, Arum touched on the globalisation of the sport.

"Look at who we signed: gold medalist Vasyl Lomachenko (Ukraine), gold medalist Egor Mekhontsev (Russia), gold medalist Ryota Murata (Japan), Zou (China), a silver medalist from Brazil (Esquiva Falcao). We're actively pursuing fighters from all over the world, because we want to be the biggest global promoter in the world. That's what we've become.” Arum said while adding that the marketing boxing in the United States is not the same.

"It's a good market, but it's certainly not growing. Boxing in the U.S. is largely dependent on two premium networks (HBO and Showtime). And as the (aging) audience for boxing begins to die out and is not replaced by the younger generation, which looks elsewhere for its sports, how long is the support from the premium networks going to last?”
