Alvarez holds the WBC, WBA, and WBO belts at super-middleweight. He's fought and won titles from super-welterweight all the way up to light heavyweight. Some of his big wins came against Edgar Berlanga, Gennady Golovkin, Sergey Kovalev, Shane Mosley, Miguel Cotto, Callum Smith, and Jaime Munguia.
Crawford just moved up to super-welterweight and won the WBA belt by beating Israil Madrimov in August. He's now a four-weight world champion and was undisputed at both super-lightweight and welterweight. His record includes wins over Errol Spence Jr, Shawn Porter, Kell Brook, Amir Khan, Ray Beltran, and Yuriorkis Gamboa.
The main issue with making this fight is the weight difference. Alvarez and Crawford last fought two weight classes apart. Crawford has said he'd move up 14 pounds to make it happen.
Both men are seen as two of the best pound-for-pound fighters in boxing. This has led to some interesting opinions from experts in the sport.
Legendary trainer Robert Garcia shared his thoughts in an interview with ESNews. When asked about Andre Ward's belief that Crawford would beat Canelo, Garcia said:
"There's no way."
While the fight remains a hot topic, there are other factors at play. Alvarez was stripped of his IBF belt for not fighting a mandatory challenger that didn't make commercial sense. And Crawford is fresh off his win over Madrimov at 154 pounds.
The boxing world will keep talking about this potential matchup. But for now, it remains just that - potential.
