Deontay Wilder expects to knock out out Chris Arreola when he defends his WBC world heavyweight title this weekend.

The Bronze Bomber will be making the fourth defence of his strap in his home state of Alabama on Saturday night and is confident of landing 36th stoppage victory from 37 fights in the paid ranks.

The 30-year-old had been due to face Alexander Povetkin in May, only for the Russian to fail a drugs test but Wilder is happy that Arreola (36-4-1, 31KOs) has stepped in.

"When it comes to Deontay Wilder, people look for the knockouts and I deliver. What separates me from other heavyweights is the fashion in which I knock guys out. I don't just knock you out, I really put you out," said Wilder.

"Arreola definitely has a style prone to a knockout. He's a pressure fighter who will come forward all night. That plays to my style. I love pressure fighters who give me a challenge. They keep me moving and thinking. I love the sweet science and the art to it.

"I have an ability to get out of bed and fight. I can do things that regular fighters can't do. I don't do miles of roadwork. I'm blessed with stamina.

"I never look at films of opponents because I want to be surprised and I want to give myself a mental challenge in there. That's what makes this sport so great.

"I'm here to defend my title against a very hungry fighter. It's a life-changing event for the man who holds the belt at the end of the night.

"I never look past anybody. But I can look through them. Before I became a champion, I said I wanted to be an active champion. Just like I was active coming up. This has been my longest time away from the ring, so if all goes well on Saturday, I want to be back in the next few months."

It will be 35-year-old Californian Arreola's third attempt to win a world title after previously falling short against Bermane Stiverne and Vitali Klitschko.

He is grateful for the chance to beome a world champion and is determined to create a legacy.

"I want to leave a legacy behind. When they talk about Chris Arreola, they're going to say 'he did it.' I took the long road but here we are now," said Arreola.

"The biggest difference between now and earlier in my career is that I'm comfortable with myself. My main motivation is being a boxer. I'm a boxer first. It's not about who has the better six-pack.

"Weaknesses are something that I have to bring out of Deontay. Someone different shows up every fight. We have a plan but we'll have to expose him while I'm in the ring. You can see videos all day, but it might not be the same guy in the ring.

"Fighting a guy like Wilder, I have to be ready for anything. But he has to be ready too. I'm no slouch. I have fire and he's another person in my way. I'm here to get it.

"There's no challenge to get ready for a fight. I'm a boxer. This is what I do and this is what I love to do. Boxing is the most gentlemanly sport there is. You beat each other up then you shake hands like nothing happened. I've been grinding every day in the gym for this."
