Golden Boy Promotions CEO Oscar De La Hoya, who promotes Mexican superstar Saul "Canelo" Alvarez (48-1-1, 34 KOs), agrees with the opinion of his fighter as it relates to a much talked about pay-per-view clash between retired former five division champion Floyd Mayweather Jr. and UFC superstar Conor McGregor.

For the last year, Mayweather and McGregor have been taunting each other in the press and on social media. McGregor is pushing to take part in a boxing match with Mayweather.

Mayweather, who retired in September 2015 and turned 40 years old on Friday, is open to the idea of fighting McGregor - if the popular MMA fighter can find a solution to get around his exclusive contract with the UFC.

Earlier this week, Canelo was asked to give his honest opinion on Mayweather-McGregor - and he called the fight "a joke" and a "black eye to boxing" if the fight was actually allowed to go forward.

If a fight with McGregor was offered to him, Canelo says he would turn it down immediately.

De La Hoya is confident the UFC will never allow McGregor to take part in such a spectacle, but he also wants McGregor to stick to his own sport. 

“No, not at all [will that fight ever happen]. With [Mayweather] it’s always been a circus all around him. I think it’ll be a disrespect to the sport of boxing [if it happens], just like Canelo said. I think they’re just totally different sports. MMA fighters should stick to the Octagon and fighters should stick to boxing. That’s just the bottom line," De La Hoya told 120 Sports. “I can’t see a boxer trying to go into the Octagon and be successful. It’d just be impossible. So there’s no way this fight will happen.”

In recent weeks, McGregor has been posting videos which showed him training to box and sparring with boxers. 

De La Hoya was not impressed by the footage.

"Like I said, it's all a circus to me. I think boxing is such a serious sport and a dangerous sport - including MMA [is also serious and dangerous]. It's just all a circus to me. I have no comments about who they should fight. Just stick to your own sport and call it a day," De La Hoya said.
