Dillian Whyte once claimed he saw Wladimir Klitschko knock former WBC heavyweight champion Deontay Wilder ‘out-cold’ during a sparring session.

Because of these quotes, we decided to take a look back at the rare sparring footage of the two heavyweights, and it's easy to see that it was rather one-sided.

Unfortunately, the footage isn't amazingly clear, nor is there a lot of it, but what we do have at our disposal shows that Klitschko was the domineering figure.

Having carried the WBA, WBO and IBF titles for a number of years, along with his brother Vitali, the Ukrainian cemented his legacy as one of the most supreme heavyweights in boxing history.

Vitali Klitschko, the older of the two brothers, held the WBC crown and then famously refused to fight his younger brother – meaning the division began to run a stale course.

Upon his retirement, Vitali would concede the green and gold strap to the Bronze Bomber, but a bout to crown an undisputed champion and the best in the game never came to fruition.

Whyte, who trained alongside Dr Steelhammer frequently, has offered an insight as to why this may have happened.

Agreeing with the words of Tyson Fury, the 34-year-old Brit disclosed that Klitschko got the better of Wilder during sparring sessions.

Towards the end of his career, Klitschko liked to bring in rising heavyweights to his hellacious training camps at the remote Stanglwirt resort in Austria and used to inflict relentless punishment on a regular basis.

Speaking about the aforementioned training camps, Whyte said: “I’ve seen [Wilder] getting knocked out, Whyte stated. “Wladimir knocked him out.

“He knew what had happened. He had his hands up. He was roughing Wlad up, bringing the smoke, and he was going wild.

“It wasn’t no knockdown, he was knocked out cold. Properly twitching as well.

“That’s why they probably didn’t want to fight Wlad, because Wlad was going to fight him as a pro and Wilder never fancied it the whole time.”

In recent times, Whyte has taunted Wilder in hope of securing a fight with the heavyweight star.

He said: “I would love to smash Deontay Wilder’s face in.

“It’s one of those fights where I would be very charged up. I would go out in the first round and just get going after him.

“It is frustrating, but it’s still a big name. He’s one of the top guys and I would love to fight him.

“He has to be serious. We offered him six, seven million dollars once and he turned it down when he was making one million dollars to fight Luis Ortiz.

“How serious is he?”

Whyte continued: “When people mention Deontay Wilder’s name to me, I just get stressed. It’s crazy, because once again someone else wants to fight me.

“[Joseph] Parker didn’t want to fight me when he had the title. I tried to fight him, no. Lucas Browne, I tried to fight him, no. All of these guys.

“Deontay Wilder, I tried to fight him when he was champion. No. Now they’ve all lost, they want to fight me after.

“If they lose, they get paid well, if they win, they’re back in the frame. These guys have got no respect.”
