Saul 'Canelo' Alvarez's legacy won't be tarnished despite his most recent setback against Dmitry Bivol according to Roy Jones Jr.

The Mexican superstar suffered a shock defeat at the hands of the Russian rendering his ambitions of becoming a two-weight undisputed world champion at both super-middleweight and light-heavyweight obsolete for the time being at least.

The dominant one-sided nature of the loss means Canelo Alvarez now needs a miracle if he is to avoid a second straight defeat in their inevitable rematch after suggesting he will activate a clause in his contract to see them go at it again for a second time.

But former four-weight world champion Jones Jr believes Alvarez's legacy is already secured having won world titles at super-welterweight, middleweight, super-middleweight, and light-heavyweight.

And even the manner of this defeat has not harmed his reputation in the slightest.

Jones told TMZ Sports: "You can't say it affects his legacy because Canelo has done a lot of good things.

"He's been a consummate professional since he was 15 years old.

"Canelo has treated us to so many fights, so many big fights, so many big nights that I can't really see it bothering his legacy.

Roy Jones Jr believes Canelo's legacy won't be tarnished despite his loss to Dmitry Bivol

"Not everybody is made to move up in weight like that, you understand me?

"There are a lot of key factors that people overlook sometimes when they're looking at guys who are trying to move up in weight.

"There are certain things that some guys just don't do a lot of and you have to be a really skilled guy in boxing to understand that.

"I understood that, so that's why I knew that to beat a guy like Bivol, it was going to be really tough.

"I said that on my podcast earlier that if Canelo pressed him, he was still going to have a hard time, but he may be pressing the whole time.

"But if he didn't press him the whole time, if he let Bivol move around and move in and out like Bivol did, there was no way he was going to beat Bivol. That was just obvious to me.

"So it doesn't do anything to his legacy because he was just trying to add and add and add. He was trying to do junior middleweight, middleweight, super middleweight, light heavyweight...

"He's already got a light heavyweight title but I guess he was going to unify it, then he was going to go up a little higher, I don't know.

"But whatever his plans were, they got derailed because he ran into a big guy who can really box and like I said, a big guy who can box usually is going to beat the smaller guy that can box."
