This is a very interesting fight, I don't have any opinion on who will win on this one. Beterbiev being a heavy puncher and Bivol is a tough opponent and a tactician, can see how to mitigate Beterbiev's explosive power. If Bivol can stand Beterbiev's punching power, I think he will win this match.
Both boxers each have good records and both are professional Russian boxers who already have quite lot of titles, Beterbiev is the only boxer with an accumulated knockout win of 100% because all his fights were finished by knockout.
Bivol himself has also fought without defeat, both fighters are undefeated fighters and fighting for the undisputed champion title will definitely change their record of losing for the first time.
I think making Beterbiev the favorite is also worth doing because he has very hard punch and is able to make his opponent fall down and not be able to continue the fight, maybe Bivol will also suffer knockout defeat.
All Arthur needs is just one clip, Bivol will not be able to balance himself the entire round. I don't know how true it was but they once had a sparring according to some boxing news which Bivol also lost. Arthur had been calling Bivol before which was unanswered.
True, this could be a test for Bivol on how tough he is. As I stated if he can absorb Beterbiev's power punches without any issue then with his style, he can outmaneuver Beterbiev and win. But who knows, I believe both camps will give us a surprise. This fight is indeed worth watching.
Bivol has good fighting tactics, he can take advantage of all existing situations, but his opponent is Beterbiev, who has hard punch and is always unpredictable.
Seeing how Beterbiev fights is truly amazing because he suddenly hits without stopping.
With the surprise blow given by Beterbiev, I believe that Bivol will definitely come under lot of pressure.
