The WBA and IBF heavyweight king is currently in the process of lining up his next fight with Joseph Parker thought to be next to take on the undefeated Brit.
The likes of Fury and Wilder are both keen on getting in the ring with him, but for now Parker looks to be the most likely contender to do battle with him as promoter Eddie Hearn continues to negotiate with his team.
However, in an explosive interview, Joshua claims he wouldn’t have a problem beating any of the highly-rated trio.
“Fury is just awkward. He is tall and I think he’s a bit of a nut-job to be honest with you,” said Joshua in an interview at Jumeirah Al Naseem in Dubai.
“I think he’s just got a bit of a screw loose. Any man with a screw loose even if it is just in business, they just have a little something that you can’t put your finger on.
“So with Fury it would be tricky to figure him out.
“I think I know what I have to do with Wilder, Parker I don’t disregard him but I think I’d smack Parker around the ring, no problem.
“Wilder, I’d knock Wilder out, it would take a bit of time but I’d definitely knock him out.
“Parker would take a bit more of a pasting but I’d get to him. Wilder, I’d knock him out with one shot. Not like I’d go in there and bang but when I catch Wilder, I’d definitely knock him out.
“And Fury would be a real breakdown job, a real gruesome type fight. Kind of like that Klitschko fight – I’ll go to hellfire and back to get the win.”
New Zealander Parker’s promoters are currently in negotations with Hearn over a fight at the 02 in March.
Parker’s promoters Duco Events held a bizarre press conference earlier this week during which they showed clips of fights in which Joshua has been hurt in as evidence their man can win.
But Joshua did not see the funny side and remains focussed on giving his best to the sport.
“The fight’s still not made,” he said. “He’s investing his time in the wrong areas – does he want publicity? Is it a PR stunt?
“We managed to work with the champions many times. I think I’ve defended it now four or five times, with no complaints.
“Against one of the all-time greats we came together and put on a great show – so what’s so difficult with fighting this little kid, doing press conferences talking a load of rubbish.
“I don’t get it, we work with people. It’s just very unprofessional of them.
“But it’s a shame because boxing has so much credibility.
“The heavy weight championship is a really well respected title to have. But stuff like that takes away from the creme de le creme of the sport.”
