After knocking out David Haye in March, you definitely get the idea that Tony 'Bomber' Bellew could be a threat in the heavyweight division.

The 34-year-old cruiserweight world champion moved up to a division to take on Haye, who was confident of an early win, before ultimately defeating him in the 11th round.

And after previously considering retirement, Bellew is now on the lookout for his next fight in arguably boxing's most competitive division right now.

But how does he think the best heavyweights around currently rank?

Bellew, who was in attendance for Anthony Joshua's knockout victory over Wladimir Klitschko last weekend has revealed his top three heavyweights in the game at the moment.

"I rate Anthony Joshua as the best heavyweight in the world, Deontay Wilder is second and Joseph Parker is third. Actually, I rate the guy I've just beaten, David Haye, above both Wilder and Parker," Bellew wrote for Sky Sports.

Bomber was talking to Sky Sports ahead of Joseph Parker's WBO title defence against Razvan Cojanu, which is the New Zealander's chance to establish himself amongst the likes of AJ.

But Bellew is not impressed with Parker's current record, citing a lack of challenging opponents with no real big name on his list and recounting his experience fighting Haye, calling out Deontay Wilder for the same reason.

He added: "I don't think Parker is a weak fighter but the heavyweight division has started to pick up again."

"Parker is having a laugh with his 22-0 record. The best name on his record is Carlos Takam. I'm 1-0 as a heavyweight and my record is better than Parker and Wilder's put together."

"That's not up for debate, it's a fact. Who the hell has Wilder beaten? Bermane Stiverne is his best win, but who's he ever beaten?"

"I defeated the last undisputed cruiserweight champion since Evander Holyfield by taking his power and dealing with him. I slapped Hayemaker 2:0 all over the ring and that's better than any win from Wilder or Parker."

There's no doubt that after beating Haye, Bellew has established himself in the heavyweight game, so he has every right to be feeling confident.

Parker is yet to truly prove himself, and Bellew has his sights set on him:

"If the figures add up, I'd fight Parker. I'm not going to go to New Zealand because I'm the third biggest draw in the heavyweight division behind Joshua and Tyson Fury.

"In terms of the calibre of fighter and the name, Parker is a step backwards for me. But he's got a world heavyweight title and that's what I want."

You'd best bring your A-game, Parker...
