Canelo Alvarez insists he doesn't view his loss to Floyd Mayweather in 2013 as a defeat, instead opting to view the fight as a "learning curve".
The now-legendary pound-for-pound great was still a young fighter when he agreed to face Mayweather in Las Vegas for the super-welterweight world titles. He had drawn once in his early career, but had otherwise been flawless in going 42-0-1 and picking up unified gold at 154lb.
However, he wasn't yet ready at just 23 years old for then 44-0 Mayweather, who bossed the fight from start-to-finish and went on to amass a 50-0 record before retiring. Afterwards, Alvarez went on a tear, winning world titles as high as light-heavyweight before eventually tasting defeat for a second time almost a decade later against Dmitry Bivol.
