Both fighters have agreed to forfeit a whopping £10 million if they withdraw from their upcoming clash.
Ahead of Fury facing Usyk, Klitschko has given the British star advice on how to beat the Ukrainian fighter.
Speaking to filmmaker Andrew Drury, the 52-year-old joked Fury must stay off junk food, alcohol and drugs.
The former world heavyweight champion said: "Not so much junk food, no alcohol, no drugs and good prepare for this fight."
Fury ballooned up in weight during his hiatus from boxing.
But he turned his life around and beat Deontay Wilder to become world champion.
The self-proclaimed 'Gypsy King' has the chance to secure undisputed status in the heavyweight division.
On Fury vs. Usyk, Klitschko, who held the WBC world heavyweight title during his legendary career, added: "Everybody expect very dramatic interesting fight, but nobody in the world can predict the decision of this fight. It’s heavyweight division, every punch make a decision.
"And that’s why it will be biggest mistake to say who will be the winner. Yes, of course I keep my fingers crossed for Usyk.
"I hope Usyk will be winner in this fight and bring WBC belt back to Ukraine. But let’s see."
Fury heads into his clash with Usyk having eked out a controversial decision victory over former UFC heavyweight king Francis Ngannou last October.
As for Usyk, he hasn't fought since last August when he stopped Daniel Dubois.
