Tony Bellew is very confident in his ability to defeat IBF, WBC, WBA, WBO cruiserweight world champion Oleksandr Usyk (15-0, 11 KOs), who is widely regarded as one of the best pound-for-pound fighters in the sport.

Bellew (30-2-1, 20 KOs), who dropped the WBC cruiserweight title in early 2017 to pursue lucrative fights with David Haye at heavyweight, is ready to return to his old division to pursue Usyk's unified crown.

Last month in Moscow, Usyk unified the entire cruiserweight division when he dominated Murat Gassiev to win the World Boxing Super Series tournament.

 Bellew is hoping that a deal is reached, and he intends to test the will and the chin of the talented Ukrainian fighter.

"I will ask a load more questions of him than he can of me, because I've been through every single scenario you can imagine in a boxing ring," Bellew told Sky Sports.

"I want all those belts. I want the fight and I want all the marbles. There's no point doing it if there's nothing on it. He is a phenomenal fighter. He is a better fighter than me. I've got no problem saying Usyk is better than me, but can he beat me? No, he can't. David Haye was better than me. Ilunga Makabu was better than me."

He wants to place Usyk in some very uncomfortable positions in the fight.

Bellew is confident that his style, combined with his unique set of skills, will be a lot for Usyk to handle in the fight,

"I will be coming with a whole new set of tools for him to deal with, than Murat Gassiev or an old Marco Huck did. I know he doesn't think it or believe it, but I can iron him out. If I hit him with the same left that I hit David Haye and Makabu, he is going," Bellew said.

"Number one, I will be the first fighter he's ever fought who is hard to hit, and I mean really hard to nail clean. Number two, I am a fighter that when he's missing, he gets counter-punched by something heavy from me. He's hitting the floor. Does he know what to do when that happens, because I do. I've been down that many times, but has he?"
