WBC heavyweight champion Tyson Fury believes Deontay Wilder is making the biggest mistake he could possibly make ahead of their upcoming trilogy clash.

He explains that Wilder has been unable to come to grips with the outcome of their second fight.

In their rematch, which took place in February 2020, Fury stopped Wilder in seven rounds to capture the WBC title.

The two rivals will collide for a third time on Saturday night at the T-Mobile Arena in Las Vegas.

Wilder has made several allegations against Fury to explain the end-result of their last fight.

He believes Fury cheated in the rematch - with a serious allegation that Fury loaded his gloves with egg weights.

Fury feels Wilder must first accept his defeat in order to move forward.

“If he went into this fight saying, ‘You know what? I got absolutely annihilated the second time, it’s probably going to happen to me again,’ then his mental attitude would definitely be of a loss straight away. But if he’s convinced himself that there’s been some skullduggery going on, maybe he thinks in his own mind he has got a better chance or something," Fury told MMA Hour.

“Acceptance is a hard thing because nobody wants to accept the truth. When I was an alcoholic, I didn’t want to be told I was an alcoholic. I didn’t want to be told I’m a fat bastard. I was just happy being that. It’s almost like this little game in your own head where you don’t want to know the truth even though you do know the truth. I always knew I was a fat bastard. I knew I was addicted to alcohol but I didn’t want it pushed in my face.

“The moment that I accepted that I had to change and I had to get help and stop what I was doing, that’s the moment I could step away from it all and start again. From what I’m hearing from this idiot here, he hasn’t accepted what’s happened to him. Therefore, without accepting defeat, you can never regain. You can never go on from that. ‘Cause you’re still dwelling on the past.

“So there’s my advice. If he’s listening or some of his team is listening — acceptance first, acknowledgment, and then you can move on.”
