Joshua added the WBA and IBO belts, vacated by Fury who is without a licence amid a hearing into alleged anti-doping offences, to his IBF strap with a thrilling 11th-round TKO of Wladimir Klitschko.
He said on Tuesday that Fury is top of his list and his British compatriot, who claims he is still the lineal champion, duly responded to those comments, saying in an Instagram post that "the world wants to see it" but that he does not believe Joshua can lace his boots up.
