Anthony Joshua bristles at the debate over his future if he loses Saturday’s career-defining rematch with Oleksandr Usyk in Jeddah.

Joshua is seeking to reclaim the WBA, IBF and WBO belts he lost to pound for pound contender Usyk through an emphatic points decision at Tottenham Hotspur Stadium last September.
