Deontay Wilder insists he's the only heavyweight with "real knockout power" and wants to face Anthony Joshua once he's beaten Luiz Ortiz in Brooklyn on November 4.
The WBC world champion last called out Joshua in the summer but the British star, who holds the WBA, IBF and IBO belts, is next facing IBF mandatory challenger Kubrat Pulev in Cardiff on October 28 after his first-choice opponent Wladimir Klitschko announced his retirement rather than take up the option of a rematch.
With Joshua red-hot favourite with Sky Bet at 1/33 to defeat the Bulgarian and Wilder also odds-on at 8/11 to see off the big Cuban a week later at The Barclays Centre, the duo could well be on for an eagerly-anticipated collision next spring.
However the test awaiting the unbeaten American (38-0, 37 KOs) is regarded to be much tougher, with Ortiz (27-0, 23 KOs) also yet to taste defeat and you can back 'King Kong', who is also the WBA's mandatory challenger to Joshua, at 11/10 to win the world title.
Wilder said: "I am the best. I am the toughest heavyweight in the division. I am the man in the division. I don't care what anybody else has going on. You've got to come through me.
"When I knock him out, I want my due respect. I'm the only American heavyweight champion of the world and I am the man. Nobody is stronger physically, mentally and spiritually. They are all scared of me.
"I'm the heavyweight in the division with real knockout power. I put grown men down easily. On November 4, Ortiz is going down. After that, you already know who is next. I'm ready to unify.
"If he's the boogeyman, I can't wait to shine a light on him because the boogeyman is only effective at night. And we're in New York so you already know what happened to King Kong in New York.
"The game plan is the same as usual. We're going to use my attributes. I'm going to set him up until the time comes. Ortiz has a great set of skills and I like his aggressive style. That's one of the reasons I chose him. I wanted to beat him to prove that I am the man.
"It definitely won't go the distance. Right now, I'm thinking about three rounds but come November 4th, it might be in the first round."
Ortiz said: "I'm ready to go and excited for the fight. I want to get to November 4 so I can do what I have to do. Wilder does a lot of talking. He's nervous and keeps forgetting the date of the fight. I think he took this fight because he has no choice and no one else to fight.
"I think Wilder is going to run in this fight. He should be careful what he says before the fight, because I think he's going to run from me. Wilder should sign his death sentence. I'm very different than anybody else that he's fought. I punch harder than anybody else. I'm going to teach him not to mess with Cubans.
"Some skeptics are talking about my age, but look at Mayweather. I still have my speed and my quickness."
