Tyson Fury has delivered a chilling warning to David Haye as the heavyweight rivals edge closer to a blockbuster bout later this year.
Fury and Haye's teams have been locked in talks this month about a possible clash, expected to be in September, and there is growing speculation about the pair finally reaching an agreement.
This grudge match should provide plenty of headlines and hype as two of the sport's biggest personalities collide, and Fury insists he has targeted Haye since becoming a paid fighter.
"It's just something that I've wanted to do for a while now," he told the Ringside Toe 2 Toe podcast.
"Since I turned professional my goal was to beat David Haye and considering I'm on that level now the fight can maybe be made, then I'd like to go in there and showcase my skills.
"You've got to give it to him, he's very fast, he's an explosive puncher and a former world champion, so it's going to look better when I knock him out."
Haye, a former world champion at heavyweight and cruiserweight, heads into the fight as a favourite, but the unbeaten Fury remains in typically confident mood.
Fury picked himself off the canvas to knockout former cruiserweight Steve Cunningham in April and he expects to deliver a similar devastating defeat to Haye.
"I tell you what's going to happen. I'm seriously going to knock David Haye out," said the former British champion.
"People have heard this talk before, but I don't say things. Like I said to Steve Cunningham, I'm going to knock you spark out, you're a cruiserweight. Dave Haye is only a cruiserweight. I'm going to knock him dead spark out. Not even a contest.
"He might jab or try and do slick movements with the head, but when someone is bulling at you, 100mph, throwing hundreds of punches. An average heavyweight throws 30-odd punches in a round. I throw 60-odd. I'm doubling any heavyweight.
"Work-rate is the key, heart and determination, fitness and stamina. If you keep knocking a stone with a hammer it's going to break. That's what's going to happen to David Haye. He's going to break."
Fury has caused plenty of controversy with outspoken outbursts on social network site Twitter, but he is not prepared to curb his behaviour.
The fighter, who is proud of his traveller heritage, hinted there will be more outrageous antics in the future if the Haye fight takes place.
"Only a fool would get upset with fools. That's why I'm a fool, but you can't take people serious because everyone has different opinions," he said.
"There is a lot of racial abuse going on, but I'm not too bothered about that. I'm big enough to take it.
"I don't think there is any such thing as being too outspoken or too controversial. The bigger the better and I'm hitting it full steam ahead, crash!"
