Tyson Fury thinks Deontay Wilder is struggling with mental health issues heading into their trilogy fight.
WBC heavyweight champion Fury is looking to end his rivalry with Wilder this Saturday night as the pair fight in Las Vegas.
Fury and Wilder fought to a controversial split draw in their first fight, but Fury would decisively win the rematch by stoppage last February.
Wilder claimed Fury cheated in their rematch by stuffing his gloves and labelled his longtime trainer Mark Breland "disloyal" for throwing in the towel.
The American has also accused Fury of "faking" his Covid-19 diagnosis that cancelled their original July 24 date for the trilogy.
But talking recently with ' Behind The Gloves ' about Wilder's conspiracy theories, Fury said Wilder is unstable going into their fight.
He said: "I don't really make nothing much of his opinions of late, because it's an opinion of an unwell person.
"I've been mentally unwell myself before and I've said some stuff when I've been mentally unwell that a sane person wouldn't say. So there's a lot of stuff going on with Deontay Wilder.
"Does that sound like a sane person? Talking to himself, saying s*** like that. I don't know, the guy's crazy."
Wilder partnered with former opponent Malik Scott shortly after his loss to Fury last year. Scott was knocked out by Wilder when they fought in 2014.
'The Bronze Bomber' has also teamed up with experienced coach and cutman Don House, who has worked with the likes of Floyd Mayweather during his career.
Will Wilder get his revenge against Fury? Let us know your verdict in the comments section below.
Wilder is known for his powerful right hand, but his new trainers revealed the heavyweight has focused on body punches as he prepares to fight Fury.
And Wilder told BT Sport Box Office he is still confident he can knockout Fury this weekend.
He said: “Well you know I have already knocked Tyson Fury out once before.
“I am sure he replays that in his head over and over again, that is why he is so brave to say I am the most dangerous man in the world because I am and it's true facts.
“My famous quote is them guys have to be perfect for ten rounds, I have to be perfect for two seconds and damn baby goodnight.
“And when you have devastating power you will always be the leader of the pack, everyone goes on about skills but it is a broken record, we have seen so many people with skills and they have lost.
“When you have power you are never out of a fight, but when it boils down to it, it is the difference and it can get you out of many different things like people have seen in my career several times.”
