Tyson Fury's father John is strangely calm on the eve of his son's legacy-defining fight against the world's most powerful heavyweight Deontay Wilder. 

"I don't do nerves, I do excitement, and that's how I am at the minute," he says. "I'm excited for it.

"I've got ultra confidence in my son's ability, I know how good he is, and I'm intrigued to see what he's going to do myself."

Big John rarely smiles, but when he talks about his sons, his eyes betray his emotions.

Tyson, aged 33, and Love Island star Tommy, aged 22, were born eleven years apart. 

But the brothers have forged a strong bond over their shared love for boxing and it is that which binds the family together.

"I always knew Tyson was going to do great things in his life," says John.

"I didn't know what. It was only until he got to about 11 or 12 years old I realised he wanted to be a boxer.

"He was always drawing pictures as a young kid of boxing rings and boxing gloves. They used to put my old kit on when they were kids.

"I only had one set of gloves so they used to have one glove on one hand and then put towels on the other hand and they used to knock lumps out of each other, him and his brother Shane, so at that moment in time when I saw them doing that I knew then he wanted to be a fighter." 

He sits back in his chair: "I always knew he was going to be a world champion, I always thought whatever Tyson puts his mind to and makes his game out of it, he'll make a great success out of it, and he has done."  

Fury Sr said he is unhappy about the decision to name an all-American panel of judges for his son's trilogy fight with Wilder but added 'he's not going to need the judges anyway'.

Fury was famously denied by the judges when he fought Wilder in 2018 but ensured there was no need for a decision the second time and John is expecting more of the same. 

"Tyson is going to destroy Deontay Wilder," says John.

"We know it's a stacked deck, we've trained for a stacked deck, he's away from home, but he's not going to need the judges anyway.

"He's not looking for points, he doesn't want a judge to do him any favours, he's going to knock him out.

"He's going to give him a bad beating as well, one he'll never forget.

"I think it'll be the end of Wilder, to tell you the truth. It could be the end of Wilder's career.

"He knows his soft points, he knows where he injured him last time, and he's going to be looking for that. 

"I don't think Wilder has got the mindset, the way he's been performing, to do anything about it. 

"He'll be a rabbit in the headlights, terror will set in, and that will be the end of him. 

"He's going to steam out, throw a few punches. We've prepared for the bombs, we've prepared for everything Wilder can bring.

"There's nothing Wilder can bring, only a lucky punch. Take his aim away, what's he got? You can have a gun, but if you can't shoot, it's no good to you, is it?"

When asked about Wilder's excuses, a storm gathers above his brows.

According to Fury Sr, Wilder has let his ego get the better of him, and he feels it will be his Achilles heel on the night.

"It's pathetic because he's embarrassed everybody back at home," he adds.

"He didn't believe he was beaten in his own mind because he's got an ego as big as Tuscaloosa where he's from, he's just got battered from pillar to post, and he can't accept it. 

"Because like I say, his ego and pride stop him from moving on from that defeat, that's why he can't learn. 

"That's why we're ultra confident because that's got in his way of taking him to the next level.

"He's never accepted defeat, he's offered a million and one reasons, all bizarre ones, to compensate for the way he feels.

"But let me tell you something, when he looks in the mirror, he knows he was soundly beaten, and he'll be terrified of Tyson deep inside.

"Behind all that exterior and all that tough guy image, he is terrified of Tyson, believe me, and when that bell goes, he's going to realise where it's at.

"Hell or high water, it's coming to breakfast for Wilder, and he knows it, too."
