Anthony Joshua has revealed he has already started plotting how to eventually defeat Oleksandr Usyk.

IBF, WBA and WBO heavyweight champion Joshua has Usyk and Kubrat Pulev as his mandatory challengers, with the latter in pole position to be his next opponent.

Undefeated Usyk defended his undisputed cruiserweight championship against Tony Bellew, a former stablemate of Joshua’s with Matchroom Boxing.

Usyk won his heavyweight debut against Chazz Witherspoon, but Joshua said: “Usyk is a great cruiserweight, the undisputed cruiserweight champion, who has decided to move up to heavyweight to mix it with the big boys.

Usyk has another option to fight Derek Chisora next. His manager Egis Klimas told Sky Sports: “If it is possible to fight in between and not to wait for another six months, I think Chisora will be a good fight for Usyk.”

That option has emerged for Usyk because Joshua’s next opponent “sounds like it will be” his IBF mandatory challenger Kubrat Pulev, according to his promoter Eddie Hearn.
