Unbeaten WBC interim-lightweight champion Ryan Garcia is being mentored by Mexican superstar Saul 'Canelo' Alvarez, who is arguably the biggest name in the sport.

They share the same head trainer in Eddy Reynoso.

Canelo has a single defeat on his pro record, which came at the hands of Floyd Mayweather Jr. in 2013 at the MGM Grand in Las Vegas.

Their contest, which took place at a catch-weight of 152-pounds, saw Mayweather easily outbox Canelo over the twelve round distance.

Canelo admits that he was too young and too inexperienced to beat Mayweather at that time.

Since then, Canelo has captured unified titles at middleweight and super middleweight - and in 2019 he even captured a world title at light heavyweight.

Mayweather retired from the sport in August of 2017, with a perfect record of 50-0, after stopping UFC superstar Conor McGregor in ten rounds.

Garcia believes the best version of Canelo would have been able to beat the best version of Mayweather.

"Canelo wins. At his best, he is much smarter and knows how to maneuver in the ring much better. Pretty Boy was good but if he went directly against Canelo, he would be knocked out. He would have to box and he (Saúl) is a big guy by nature," Garcia told ESPN.

While Garcia respects the skills and ability of Mayweather, he was never in favor of the image that he portrayed to the public - as an athlete consumed by money and material things.

"What I had a problem with [when it came to] Floyd was how he represented himself when he got to the top. He threw around the image of glorifying money. I don't like that," Garcia said.
