If I’m really pushed, I just don’t think Bivol will have the firepower to keep Beterbiev off. I see Beterbiev will wear him down and maybe get a stoppage around the ninth or 10th round.
“But I likewise would not be stunned if we see an extremely regimented efficiency from Bivol where he outboxes Beterbiev, struck him and relocate him, comparable to just how he did versus Saul ‘Canelo’ Alvarez.”
WBC lightweight champion Skye Nicolson: “It’s the common fighter v fighter, and I need to back the fighter. I discover it difficult to see Bivol being captured in a scenario he does not intend to remain in. He’s so proficient at managing the range and speed of the battle.
“But if anyone can do it, it’s Beterbiev. My heart says Bivol.”
Retired globe champ Barry Jones: “Beterbiev has to be a slight favourite. He’s knocked out punchers , he’s knocked out boxers and he can knock you out in the first round or the 12th. There is no round, second or minute when you’re really truly safe with him.
“But I will certainly still opt forBivol I simply sense that his knowledge, perseverance, self-control and peace of method could simply suffice to ride the harmful minutes and obtain him via in a close choice.
“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.”
British heavyweight champ Fabio Wardley: “I am edging toward Bivol but this is probably one of the hardest fights to predict in boxing at the moment. It’s a real pick ’em fight with two men with completely different styles. Beterbiev is a destroyer who can clean through everyone. Bivol has great power but is such a clean and precise boxer.
“It’s an inquiry of that can apply their design best on the evening and make the influence.”
Heavyweight Frazer Clarke: ” I maintain transforming my mind. I’ve been stating Beterbiev during yet I currently assume Bivol might take this set. It’s a top quality 50/50, however.”

Not enormous, yet at any type of factor he might switch over Bivol’s lights out. But I am going Bivol in a consentaneous choice yet an extremely close battle. What I indicate by that is the rounds will certainly suffice. I am opting for the toreador in this battle yet I would not place my residence on it.”
Bivol’s promoter Eddie Hearn: “When you combat Beterbiev, it resembles a ticking time bomb. The rate of that time bomb relies on the challenger. Dmitry has the capability to make that tick actually sluggish. How sluggish can he make it tick? The boom factor is 12 rounds.

“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.”
English cruiserweight champ Viddal Riley: “I’m going with Bivol. He has the better movement, better flow and will be able to outbox Beterbiev for the majority of the rounds. But as we get into the later rounds, it will turn into a war.”
