‘A punch like a horse kick’ – Oleksandr Usyk vs Daniel Dubois predicted by Joe Joyce, Frank Warren, Carl Frampton and more

Daniel Dubois has a mountain to climb on Saturday night in the form of unified heavyweight world champion Oleksandr Usyk.

The Brit will travel to Poland in an attempt to claim the WBA, WBO and IBF heavyweight world titles, which Usyk currently holds.

The Ukrainian is unbeaten as a professional, having won the undisputed cruiserweight world titles, before moving up to heavyweight and becoming champion once again.

This will be Usyk's fifth fight in boxing's glamour division and he has previously beaten Chazz Witherspoon, Derek Chisora and Anthony Joshua twice, but he has never come up against a young, hungry, powerful heavyweight quite like Dubois.

'Dynamite' Dubois' huge punch has not been able to carry him through every fight, as he suffered one loss as a pro against Joe Joyce.

Here's how 'The Juggernaut' himself and others think it will play out on Saturday.

Joe Joyce: Fought Dubois in the pros and Usyk in the amateurs

"I think Usyk is going to dance round him, Dubois won’t be able to hit him, he certainly couldn’t hit me when we fought, so he’s not going to be able to hit Usyk," Joyce told talkSPORT.

"Dubois hits hard but you can’t hit someone who is going to be moving and he’s going to dance rings around him, peppering him with shots.

"There’s a small chance Dubois hits him with a big shot, but I can’t see it."

David Haye: Former cruiserweight and heavyweight world champion

“[Dubois] has a huge chance. He’s a heavyweight, he’s young, fresh and big. He packs a punch.

“Oleksandr Usyk, if you want to play the boxing game with him, as Anthony Joshua tried to do on two occasions, you will come off second best.

“I feel like Dubois’ chance and opportunity is to watch the Derek Chisora fight. What Chisora did was use what he had, which was size and a good chin.

“He got close to Usyk and didn’t want to play the long range game. Got inside, the back of the head, the kidneys. There was a break in the action and Usyk’s legs were slower.

“If Dubois is willing to go through those first two rounds where he may get peppered, may get dropped. He’s got to not put himself in that Usyk zone, which is at the end of his punches."

Alex Krassyuk - Oleksandr Usyk's promoter

Krassyuk is backing his man, but he is not writing Dubois off, as he recalled one notable boxing upset.

"Everyone can knock the guy out when he comes to the ring," Krassyuk told talkSPORT.

"Just remember when Hasim Rahman fought Lennox Lewis for the first time. Who could imagine? No-one could, and the same thing could happen in this fight.

"But, Usyk is really professional and he takes it really seriously no matter who his opponent is, the training camp is the same, same exercises, same discipline, same regime, getting up at 5am, it's the same.

"The thing that can differ is the motivation, because when you're supposed to fight Tyson Fury you have in your mind that you're going to overcome a substantial challenge in your life.

"But, when it comes to Daniel Dubois, who is the underdog in the fight, it swaps the mindset, but for Usyk it is absolutely manageable."
