Beterbiev age 30-34 would massacre Canelo. And viciously beat him up and force Canelo to submit in pain. There is a reason why Canelo has an allergy to anybody decent who is younger than mid 30s.
I think the fight could happen if Beterbiev holds a strap 2 years from now, but certainly not before then.
Beterviev will win the initial rounds then get grinded down by Alvarez until either he gets knocked out or losses by decision. Which will only make canelo's fans worship him even harder for beating a boxer with no defeats and 18 wins by the way of knockout without actually knowing who Beterviev is.
You’ve got it backwards, Canelo will win the early rounds before Beterbiev grinds him down and stops him. Canelo will be feeling emasculated by Beterbiev’s strength, I think he will wilt with the relentless punishment.
Beterbiev is very hittable, he has weak defence. Canelo would dismantle him before Beterbiev gets to him. Canelo by KO in round 10 or 11.
He could've unified with Beterbiev after cherrypicking the shell of Kovalev's drunkard ghost (aka ''the best 175 pounder in the world'' according to Clennocchio ) the WBO strap but, just like I told you all he would, he dropped that belt like it was molten lead and hightailed it back down to a graveyard division to unify down there against nonthreatening driving instructors, dog trainers and soup kitchen volunteers who couldn't punch the wings off a moth if they were in a rage. Beterbiev was still too fresh, young and way too dangerous for Clen back then just like Big G was when Clen was covering in fear in a puddle of pee in the darkest corner of the chicken coop when he was shamelessly ducking him. Bivol was much more active and dazzling against a far higher level of opposition than he's looked flat against since returning from the 19 months of inactivity back then too. Beterbiev is 37 now, already past his best and his reaction times have clearly slowed, but Clen still hasn't seen the required amount of decline in him for him to pass the Yellow Clenelo rotten fruit picking test. Hence why he's opted to face GGG's 40 y/o shot ghost next if he gets past Bivol and will age Beterbiev out until he's at least 38, just like he did with GGG not once but twice.
