The former heavyweight king made the boast ahead of his return to action this weekend from a 31-month absence.
Fury, 27, takes on cruiserweight Sefer Seferi in a bid to shake off the cobwebs but is massively confident he could defeat any of the current crop of top division stars.
“If I can’t wipe the floor with the whole of the current heavyweight division, I will get on my knees in front of whoever beats me and kiss their feet. That is how confident I am of annihilating all of them,” Fury told The London Evening Standard.
“The great Sugar Ray Leonard came back after three years in 1987 to fight one of the greatest middleweights in Marvin Hagler. And he still beat him.
“So if I can’t come back and beat someone, then I’m clearly no good.
“If I am as good as I think I am, then I should be able to beat them all. If I can’t win against Anthony Joshua, Deontay Wilder, Sefer Seferi and whoever else wants to fight, then I will say I never was any good and I should never have been boxing. I should beat Seferi comfortably.
“If I’m useless, I’ll lose. You can’t say fairer than that,” he added.
Trainer Ben Davison, who has overseen Fury’s transformation in recent months, says Fury has youth on his side.
“Muhammad Ali had great wins after he came back, even though he lost the first big fight against Joe Frazier in 1971, which was down to tactics,” said Davison.
“Wladimir Klitschko and his brother Vitali both had great wins as heavyweight champions after they had suffered defeats.
“Lots of fighters have come back. And Tyson is still undefeated.”
Initially staying busy, Fury is expected to fight three times in 2018 before stepping up his opposition next year with a world ranking in sight.
