The IBO, WBA and WBO heavyweight champion had to watch on as WBC holder Wilder and Tyson Fury fought out a thrilling draw in Los Angeles a fortnight ago.
Anthony Joshua has made it clear he wants "just" Deontay Wilder next, with Eddie Hearn admitting Jarrell Miller and the victor of Dillian Whyte against Derek Chisora, could step in if it doesn't happen.
Joshua's promoter Eddie Hearn is keen to have Wilder face "AJ" on April 13, the date for the Olympic gold medallist's next Wembley bout. The bout might even land opposite of Anthony Joshua's next scheduled fight on April 13. He's more interested in fighting Tyson Fury.
"He could have had this opportunity, he had many opportunities; he could have fought Luis Ortiz, he could have fought me, he had a chance to fight [Tyson] Fury".
"I can't control what Wilder or Fury do and say".
Now the main focus for Wilder is certainly a highly anticipated rematch with Fury - likely to take place in the first half of 2019. I can control what I say and what I do.
"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".More news: SDF Continues to Advance Into Hajin, Last Daesh Stronghold in Syria - Coalition

"When I was joining the heavyweight ranks, nobody told me about [being] lineal champion", Joshua said.
The former heavyweight world champion hung up his gloves after being stopped by Joshua in a epic clash at Wembley previous year, but now seems tempted by the possibility of getting a second bite at the cherry amid uncertainty over the Brit's next opponent. I don't know where this lineal has popped out of the woodwork from.
"I think he text (ed) AJ and said: "I want to come back".
Boxing legend, Oscar De La Hoya has rated Nigerian-born British world heavyweight champion, Anthony Olaseni Joshua as the best in his class for now..
And he believes the American, who wants to unify the heavyweight division, should be doing everything in his power to make the fight happen.
Hearn talked up Joshua's opponent for April 13th, naming a bunch of potential fighters including Klitschko.
"Five years in, seven world title defenses and I'm running the game - I mean business".
