Former unified heavyweight champion Tyson Fury (25-0, 18 KOs) has issued a very strong warning to Tony Bellew, who's been calling for a showdown in the near future.

Bellew, who fought most of his career at light heavyweight before making the jump to cruiserweight and then eventually to heavyweight, believes he could beat Fury.

Earlier this month, Bellew (30-2-1, 20 KOs) crushed former heavyweight champion David Haye in five rounds.

After the fight, Bellew was very quick to call for a fight with Fury.

“I’d love Tyson Fury. I’d love to knock Tyson Fury out. I know people think I’m crazy but I know I can do it,” Bellew said.

Bellew's two fights at the heavyweight limit have both come against Haye.

Fury, at 6'9 and usually around 250-pounds when he's in form, has a massive size advantage over Bellew.

"If he steps in the ring with the Gypsy King and I unleash hellfire on him, he’s only a small man and I could damage and hurt him properly. You ain’t messing with a David Haye who’s 20 years out of date. You’re messing with someone 6ft 9in, 19 stone, in the prime of me life who can knock a wall down - one of the hardest punchers in heavyweight boxing, but they don’t know it," Fury told Fighthype.com.

"If I go in there and hurt him, what good is that? How does that make me feel, knowing he shouldn’t even be in the ring anyway? Listen, we all need money but he doesn’t need money that badly to go and lose his senses and get smashed to pieces.

"And all this ‘he could knock me out’, please. I could let Tony Bellew hit me right here [to the chin] and he wouldn’t hurt me. He doesn’t want no part of this, trust me on that."

Fury, who has been inactive since November of 2015 when he shocked Wladimir Klitschko with a twelve round unanimous decision to capture four world titles, will finally return to the ring on June 9th in Manchester.
