“I’ll demolish Joshua. I’ll get even better from here. after “Anthony Joshua sends

Anthony joshua 34, was ringside for the biggest victory of Dubois’ career but has warned him he’ll suffer another setback in his world title hopes when they throw down.

Taking to Instagram to share a photo of himself watching the fight, AJ wrote: “The hardest part about my job is realising you have to ruin someone else’s dream to achieve yours.”

Dubois, 26, suffered heartache in his first crack at heavyweight gold against undisputed champion Oleksandr Usyk last August.

And he’s vowed to “demolish” Joshua on his way to a second crack at a world title.

He said: “That’s what I’ve been hearing [that Joshua could be next], so let’s see.

“[Being world champion] is a dream.

“From challenging for the world title to getting the chance to win the damn thing outright, that’s what I want.

“I’ll demolish Joshua. I’ll get even better from here.”

Joshua has rediscovered his mojo with four wins on the bounce, the most recent being his brutal second-round KO of former UFC heavyweight champion Francis Ngannou.

But he’s refusing to overlook Dubois, who bounced back from his TKO loss to Usyk with successive stoppages of Jarrell Miller and Hrgovic.

The former two-time unified heavyweight champion said: “I’ve got to pick them off one by one.

“It’s not going to be easy, but that’s my mentality. So come one, come all…

“He [Dubois] has been in tougher fights, so he becomes hardened.

“He has worked his way up the ladder, we’ll see what happens in the near future.
