WBO, WBA, IBF, IBO Anthony Joshua (22-0, 21 KOs) feels very confident of beating both Tyson Fury and WBC champion Deontay Wilder.

Joshua is a superstar in the UK, and he's finally expanding his profile to other markets.

For the first time in his career, Joshua will make his American debut on June 1 at Madison Square Garden in New York City, against undefeated Jarrell Miller.

Joshua is a 5-1 favorite against Miller, and not many experts are picking the challenger to pull off the upset.

The biggest challenges for Joshua would be fights against Wilder and Fury - who back in December fought to a controversial twelve round split draw.

Joshua believes he can dismantle either boxer with different strategic methods.

"Fury, I’m just going to knock him out. No nonsense, none of this jab-for-jab nonsense. Just work him, work him, work him. With Wilder, I can outbox Wilder. No problem. Fury’s a bit more elusive, so I have to just kind of pin him down a bit more, then do what I want to do," Joshua told The New York Times.

As far as Miller, Joshua plans to issue a lot of punishment.

The two boxer traded some very harsh words earlier this week at a New York press conference to announce their fight.

Due to the heated rivalry, Joshua has one fight strategy in mind.

"Just beat him up. There’s no real complicated stuff when it come to boxing. Just. Beat. Him. Up. You hit them hard, and you earn their respect. What happens is, their spirit is like 100 percent, then you’ve got to take them down to 80, to 60, to 40, to 20, until they got nothing left. And then — if he stays in there — it’s how much heart he has," Joshua said.

"Yeah, he’s a big guy. It’s a bigger target. He’s obviously going to be firing back, so I have to be on my A game."
