Joshua and Wilder’s camps engaged in talks in the summer but could not agree on a fight deal which would see one man unify the division.
Wilder quickly moved on and fought Tyson Fury, whose relinquished titles had been taken by Joshua during his 31-month hiatus from the ring.
The Bronze Bomber defended his WBC strap against Fury on December 1, keeping the gold-plated green leather belt courtesy of a controversial split decision draw.
The WBC has since sanctioned a rematch between Wilder and Fury, who are set to pick up talks after Christmas for a fight in the spring.
“I’m willing to fight Deontay Wilder, April 13 in London,” Joshua asserted.
“I don’t know what more I have to do to get that message across. I can’t control what Deontay Wilder does, I can’t control what Tyson Fury does, or even as far as what they say.
“But what I can do is control what I say and what I’m doing. I made sure with the negotiations I booked the date in advance, set the venue in advance.
“And I’m making my point clear in front of everyone watching, I’m willing to fight any one of these guys, especially the champion, Deontay Wilder, April 13 at Wembley. What more can I say?
“I’m not interested in Tyson Fury – he’s not the champion, that’s where I’m coming from.”
Fury has assumed the title of the division’s ‘lineal champion’ after beating then-unified champion Wladimir Klitschko in November 2015 and not losing since.
Joshua was dismissive of the title, however, scoffing: “That lineal status. When I was joining the heavyweight ranks, no one told me about the lineal champion.
“I knew about WBC, IBO, IBF, WBA and WBO. And I’ve got my hands on four of them. So I don’t know where this ‘lineal’ has just popped out of the woodworks from.
“But if I’ve got to get my hands on that too, and that’s what the world’s interested in, Fury can step in if he’s serious.
“I want to fight the champions. I’m the one leading the back – I’ve been doing that since I made my debut.
“Five years in, seven world title defences and I’m running the game, I mean business.
“I don’t know what more I have to do to get that message across to the world.”
