Fury took part in a training camp with Klitschko in Austria in 2010 when the IBF, WBA and WBO super heavyweight champion was preparing to face another Briton in Dereck Chisora.
Chisora lost that rearranged fight in 2012 and was beaten convincingly by Fury last month in a contest where a mandatory challenge to Klitschko’s WBO title was at stake.
Fury, who is expected to fight a to-be-confirmed opponent at London’s O2 Arena on February 28, does not expect Klitschko to go through with the bout.
Should the promoters fail to come to a deal the bout would go to purse bids, with the possibility Klitschko would vacate the titles, giving Fury a title bout next summer anyway.
“I’m a million per cent convinced this fight ain’t going to happen,” Fury said.
“I don’t think Wladimir will fight me. If he does it’s a miracle.
“I don’t care what the promoters say, I’ve looked in his eyes and I saw fear. I know he’s not going to fight me.
“If it does happen he’ll get knocked out after seven, eight rounds, after being involved in a bit of a brawl.
“He’s old, he gets tired fast and I’ll knock him out for sure.
“When I do I’ll unify the division against (Bermane) Stiverne or (Deontay) Wilder.
“And then, I might take one more, two more defences, take a bit of a break. And then we’ll see, wait for the next big challenger. I’ve got it mapped out.”
Fury’s certainty over the Klitschko fight is based on the wisdom of late trainer Emanuel Steward.
“Emanuel Steward was a very inspirational trainer and people listen to what he has to say,” Fury added.
“He told Wladimir that I was the heir to the throne and within two years I’d take his title off him. He was right about that.”
