Tyson Fury has predicted he will knock out Anthony Joshua inside three rounds - with a left hook.

The heavyweight world champions are on a collision course for 2021, assuming they both come through their respective title defences.

Fury must defeat Deontay Wilder for a second time while Joshua is due to defend his three belts against mandatory challenger Kubrat Pulev.

Those fights are expected to take place this winter with Fury and Joshua then meeting early next year, likely in Saudi Arabia.

And Fury expects an easy night as he bids to become the first undisputed heavyweight champion since Lennox Lewis.

Tyson Fury has promised to KO Anthony Joshua

"AJ's style is tailor made for mine. He's an upright fighter walking forward with a classic defence," he told Sky Sports. "Strong and powerful. He's got no footwork, hardly any resilience. And he's a bit gutless when it comes down to getting clipped.

"I think I'd knock him out in round two, three rounds. First time I connect on him, his legs will do a dance and I'll just jump on him like the little fat kid did in America that time.

"It's going to be a left hook to the temple, and you're going to see him doing a Bambi dance all over the ring."

Joshua's promoter Eddie Hearn believes the rivals could fight twice next year.

Joshua was dropped three times by Andy Ruiz

And Fury added: "Eddie Hearn talks a lot of hot air as usual.

"I've been offering to fight Joshua for quite a while. I've been trying to make that fight happen for the last five years and it's not happened at all.

"Eddie's obviously Joshua's promoter, so he'll have to be speaking to my team to make the fight happen, give the fans what they want and stop running away from the biggest fight since Lennox fought Frank Bruno.

"Have the guts to step up to the plate and get flattened, son!"
