Dillian Whyte says he is ready to face fellow Britons Tyson Fury or Anthony Joshua and is "hungry" for the chance to become world heavyweight champion.
Whyte, who will fight Russia's Alexander Povetkin on 2 May in Manchester, is the mandatory challenger for the WBC world heavyweight title.
But the WBC says his tilt at the crown will not arrive until February 2021.
WBC champion Fury and Joshua, who holds the IBF, WBA and WBO belts, could meet in a unification bout before that.
