Joshua missed out on the opportunity to unify his WBA, IBF and WBO world titles against WBC king Wilder after the American snubbed any fight offers.
For the same reason AJ, 29, saw a mammoth domestic clash with Fury disintegrate –leaving the unified champion to make his Stateside debut on June 1 against American Jarrell Miller.
“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.”
As Joshua prepares to defend his trio of world titles in the summer at Madison Square, he faces a 6ft 4ins – 315lb challenger in “Big Baby” Miller.
Joshua added: “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.
“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.”
Despite publicly expressing frustration a deal could not be agreed with Wilder or Fury – Team AJ took consolation that the Miller fight will at least boost the Brit’s profile Stateside.
But Miller has used trash-talk to entice fight fans, and possibly AJ – however, Joshua revealed Big Baby will be “irrelevant” come June 2, with the champion already adding Cuban Luis Ortiz on the list of potential next opponent.
AJ said: “June 2 he’ll be irrelevant. So he’s relevant for the next 14 weeks. And then when it’s all done, I’ll move on to looking at Wilder, Fury or Luis Ortiz.”
