This is a 3 belt unification at super middleweight between the best fighter on the planet and Billy Joe Saunders.
Canelo Alvarez is great technically and uses smart pressure to break down his opponents generally. He’s almost always in range but due to his great defence it’s very hard to hit him and he’ll counter as soon as his opponents slip up.
Billy Joe Saunders is a southpaw who’s also fairly good technically but unlike the southpaw’s that have given Canelo trouble in the past he isn’t slick. He’ll mostly be in range for the majority of the fight and rely on his reflexes to keep him out of trouble.

I think Canelo will simply be too good for him as Saunders has in my opinion looked fairly bad as a super middleweight while Canelo seems to be in his prime and is putting together incredible performance after incredible performance.
