Retired globe champ Barry Jones: “Beterbiev must be a slight favorite. He’s knocked out punchers , he’s knocked out boxers and he can knock you out within the first spherical or the twelfth. There isn’t any spherical, second or minute if you’re actually really secure with him.
“But I’ll definitely nonetheless go forBivol I merely sense that his data, perseverance, self-control and peace of methodology may merely suffice to experience the dangerous minutes and procure him by way of in an in depth alternative.
“Bivol might have to get off the floor a couple of times but I think he could have an early enough lead to sneak home.”

It’s an actual decide ’em struggle with two males with utterly completely different types. Beterbiev is a destroyer who can clear via everybody. Bivol has nice energy however is such a clear and exact boxer.
“It’s an inquiry of that can apply their design best on the evening and make the influence.”

Not monumental, but at any sort of issue he would possibly change over Bivol’s lights out. But I’m going Bivol in a consentaneous alternative but an especially shut battle. What I point out by that’s the rounds will definitely suffice. I’m choosing the toreador on this battle but I’d not place my residence on it.”
Bivol’s promoter Eddie Hearn: “When you fight Beterbiev, it resembles a ticking time bomb. The charge of that point bomb depends on the challenger. Dmitry has the aptitude to make that tick truly sluggish. How sluggish can he make it tick? The increase issue is 12 rounds.
“Beterbiev is going to get you, but how quick can he get you and how long do you have left when he does get you? The only person who can beat Beterbiev right now is Bivol.”

“Bivol is obviously exceptionally good and has unbelievable footwork so I wouldn’t be surprised if he did win. But I’ve always felt Bivol, apart from against Saul ‘Canelo’ Alvarez, has done just enough to win fights and I’m not sure that will be enough against Beterbiev. I don’t think he hits hard enough to command Beterbiev’s respect.”
