Oleksandr Usyk is up there with the likes of Muhammad Ali and Sugar Ray Leonard among boxing’s greatest fighters.That’s according to talkSPORT pundits Adam Catterall, Spencer Oliver, and Gareth A. Davies, as well as British heavyweight boxer Dave Allen, who all agreed Usyk’s second victory over Dubois places him in a class to which not many belong.Usyk knocked out Dubois after five rounds to become undisputed heavyweight champion once againGettyUsyk dominated Dubois at Wembley Stadium on Saturday night, stunning the Brit with a flurry of shots before a left hand sent ‘Triple D’ crashing to the canvas, and he was counted out.The Ukrainian’s performance settled any doubts over how he would fare against Dubois in their rematch following the pair’s controversial first meeting in Poland years ago.It also proved that Usyk is a one-of-a-kind fighter, who is now being viewed as one of the best boxing has ever seen.“You’re talking about greatness, yes, Muhammad Ali will go down and he’ll always be the greatest,” ex-European super bantamweight champion Oliver explained on talkSPORT Boxing live from Wembley on Saturday night.“But let’s talk about who’s the best: Oleksandr Usyk, his name is right up there.“You don’t become a three-time undisputed world champion, do what he’s done, jump through the weight divisions, beat everyone of that era, and that performance that he put in tonight was the best Oleksandry Usyk I’ve actually seen.“You’ve got to put him up there. That was phenomenal. People were talking about age, that he was showing signs of wear and tear after the two [Tyson] Fury fights, well, he answered all those questions.“He looked young, he looked fresh, and he made a potentially difficult fight easy.”Usyk was fresh off two successive wins in Saudi Arabia over Fury, who has since called the Ukrainian out for a trilogy bout next year.‘The Cat’ insisted he was purely focused on resting when speaking in the ring after his fight, with WBO interim heavyweight champion Joseph Parker also looking a piece of the new undisputed champion.talkSPORT presenters believe Usyk is up there with the very bestGettyUsyk made light work of Dubois at Wembley on Saturday nightGettyWBA inter-continental heavyweight champion Allen was asked if he believes Usyk would have beaten some of the all-time greats like Ali, Evander Holyfield, and George Foreman.“It’s very difficult to say,” ‘The White Rhino’ responded.“Obviously with time there’s been improvements in strength and conditioning, nutrition and all the rest of it.“You cannot compare different generations, but he will go down as one of the best of all time.“Of course, he belongs in the conversation with Sugar Ray Leonard, Ray Robinson, I put him in that bracket, I really do.“Because it’s 2025 and he’s still active, it’s difficult to do that. You tend to appreciate things more when they’re gone. Allen said Usyk will be remembered as an all time greatGetty‘The Cat’ is the undisputed champion at heavyweight for the third time now“So in 20 years’ time, I think people will go, ‘Usyk was as good as Robinson, as good as Leonard,’ but right now it’s a bit of a controversial thing to say.”Oliver chimed in once again to assert his stance on Usyk being one of the greatest.“Usyk just went out there and delivered, that’s what great fighters do,” he said.“You get good champions and you get great fighters, the ones that can adapt while it’s going, and Oleksandr Usyk is the master of that. “You can’t deny that, and Dave’s right in what he says… we remember Lennox Lewis.“I was boxing on all Lennox Lewis’ undercards back in the day and they were talking about Lennox Lewis, coming after Mike Tyson and looking at Larry Holmes and all the rest of them. “People asked, ‘Where does he sit in it?’ and others said, ‘Well, yeah, he’s a good heavyweight and only time will tell.’“Now we look at it and go, ‘Lennox is one of the greatest, if not the greatest, to ever do it!”“Usyk is in that argument; you can’t not deny that guy is as good as any of them.”Davies concluded: “Usyk would have given Lennox Lewis the same problems that Evander Holyfield gave him in my view because of that incredible movement of the feet, the magician’s hands, the angles he creates… all those southpaw skills, the angles that he creates as a lefty.”
