WBC heavyweight champion Tyson Fury is confident that he's a bigger puncher than domestic rival Anthony Joshua, who holds the WBO, WBA, IBF, IBO world titles.

There are serious discussions when it comes to Fury and Joshua colliding in a two-fight series in 2021.

Joshua will also have to come out on top, when he faces mandatory challenger Kubrat Pulev.

Should both champions win, their initial fight will potentially happen in the first half of next year - but that depends on the deal being finalized and the restrictions pertaining to the coronavirus. Fury vs. Joshua will certainly require a crowd of some sort, with numerous locations likely to pursue the rights to host that event.

"I turned pro at 19. As a child, I was boxing men. [Joshua] never turned pro until he was mid-20s, when he was a man. So I was learning as a young kid. If I had turned pro at 25, 26, then I'd have knocked all the people out who went the distance with me when I was a young boy," Fury told the Lockdown Lowdown show.

"I've never been a stand-still man who lands big shots, because I'm a slick boxer. I've just knocked out the heaviest puncher in boxing history. Andy Ruiz is not a big puncher but he knocked out Anthony Joshua.

"So I'd say I am a harder puncher than him. There's people who have sparred both of us and quite a few of them have said it as well. But it's not about who can punch hardest - it's about the skill that goes behind it. I am still unbeaten in a 12-year professional career. I'm a force to be reckoned with."
