Tyson Fury insists that Anthony Joshua will be 'a lot easier' to beat than Deontay Wilder.
Joshua, 31, will defend his WBO, IBF and IBO belts and his WBA (Super) title against fellow former Olympic champion Oleksandr Usyk in London later this month.
Fury meanwhile is currently preparing for his trilogy fight with Wilder two weeks later.
Joshua is one of, if not the biggest star in the sport, courtesy of Eddie Hearn's well-oiled PR machine sponsored by major brands like Under Armour, Hugo Boss and Jaguar Land Rover.
However, Fury claims that it's all just a ruse to hide the man behind the mask.
When asked if he has ever met the 'true' Joshua, Fury told The Lowdown: "Yes, yes, I have, yep.
"I have definitely encountered the true Anthony Joshua.
"Not a nice person, sort of a bully, someone who thought he was going to sort of put the bluff on me, and that's what type of person he is.
"I don't think you need to be a rocket scientist to figure that out.
"I once had the opportunity to see the real Femi.
"He phoned me up one day in a mood saying he was going to do this to me and do that to me and it didn't fare too well for him to be fair let's just say that."
Should the British duo win their respective bouts this autumn, both camps are likely to begin talks over a highly-anticipated undisputed showdown in 2022.
Despite having beaten Wilder previously, Fury believes it will be 'a lot easier' to defeat Joshua.
"I just told him the truth and the truth always hurts," he explained.
"Nothing will ever cut you deeper than the truth because the truth will always set you free and sometimes people hide behind the truth.
"They hide behind smoke and mirrors and lies and they love it that way.
"But the truth will always set everyone free and it cuts deepest, like an alcoholic does never want to be told he's an alcoholic, a drug addict never wants to be told they're druggies, they always just like to get away from it.
"The truth hurts; if you're a bad person, you don't want to be told you're a bad person, you just want to be left alone, do your own thing, and get on with being a bad person.
"So the truth always cuts deep, no matter if you're good, bad or indifferent, the truth will always cut deepest.
"I don't know him, I don't want to know him, I've got no time for him, he's just another bare bum in the shower for me, and when I come across him in the boxing ring, I will obliterate him, and it will be an easy, easy fight.
"A lot easier than Deontay Wilder will ever know how to be and that was pretty easy, that was one of the easiest fights I've ever had, but AJ will be easier than that."News Now - Sport News
