The former heavyweight world champion has been in impressive form since linking up with the trainer last year and the veteran fighter thinks Joshua should now be able to avenge his two losses to Oleksandr Usyk.

Chisora told Crypto Casino LTD: "AJ would wipe the floor with Usyk under Ben Davison, I don't think it would go six rounds.

"He chucked a couple jabs against Otto Wallin [in December] and everything else was power and he's mixing up head and body.

"That said, with current records and past performances, right now the best heavyweight in the world is Usyk, gold medalist and undisputed cruiserweight champion.

"He came up at heavyweight and has taken over, and in one more fight he can prove he is the pound-for-pound the best fighter and make history for Ukraine."

Chisora is even confident that a revitalised Joshua could defeat his British rival Tyson Fury if the pair ever end up in the ring together.

He said: "I'm picking AJ over Fury all day long if it gets made.

"He's a friend and we went to the same amateur club, but his power will be too much for Fury, he'd have so much ferociousness saved for that fight, and you must remember that Ben Davison knows Tyson Fury very well, so I think AJ [wins]."
