Deontay Wilder insists a unification fight with Anthony Joshua is still “going to happen” and wants to punish the British star for the sleepless nights caused by their lengthy negotiations.

The WBC champion flew into London for a press conference with Tyson Fury ahead of his next title fight in Los Angeles on December 1, although Joshua remains a long-term target for the American.

Talks have broken down for a bumper bout between the duo, with all the world titles at stake, but Wilder remains eager to share the ring with Joshua and hopes it will create huge public demand.

Promoter Eddie Hearn says a showdown with Wilder is the ‘sole focus’ ahead of Joshua’s next title fight at Wembley on April 13, and the ‘Bronze Bomber’ is willing to return to Britain, having defeated Audley Harrison in Sheffield in 2013.

Dillian Whyte has also been pursuing a WBC title shot as the WBC’s no 1 ranked contender, but Wilder says he will only face the Brixton man if he defeats Luis Ortiz, his last opponent in March.
