Former undisputed heavyweight champion Tyson Fury (25-0, 18 KOs) believes that he would seriously hurt Tony Bellew if they stepped in the ring against each other.

Earlier this month, Bellew (30-2-1, 20 KOs) crushed former two division champion David Haye in five rounds at the O2 Arena in Las Vegas.

Fury is back in the ring on June 9th, when he takes on Sefer Seferi in Manchester.

For Fury, it will be his first fight since his huge upset win over Wladimir Klitschko in October 2015, when he capture the WBO, IBF, WBA, IBO world titles.

All of those belts are now owned by Anthony Joshua - who Fury would love to get in the ring.

On paper, the fight is a mismatch of size - with 6'9 Fury holding a significant advantage.

Bellew, a former WBC cruiserweight champion, moved up to the heavyweight division last March for his initial fight with Haye - and Bellew stopped him in the eleventh round.

A few years ago, Bellew was competing as a light heavyweight. His last bout at the weight, in 2013, saw him getting knocked out by current WBC champion Adonis Stevenson. It was the last time Bellew tasted defeat.

According to Bellew, he would - without question - score a knockout victory over Fury.

And he also feels confident in beating Fury in a war of words.

“I’ll put him fast asleep – I have no doubt about it. His words were ‘I’m not going to fight Tony Bellew – I don’t want to hurt a cruiserweight' but he’s only fighting a cruiserweight who’s smaller than me, so what’s going on?," Bellew told TalkSport.

“It’s unbelievable. Think before you speak, my friend. Ultimately, I like Tyson – it would be great banter. I don’t think he could live with me, I don’t care how good his banter is. No one’s beating a scouser when it comes to banter.”
