David Haye claims Wladimir Klitschko would need a chin transplant to save him from being "destroyed" in their July 2 clash.
The WBA heavyweight champion will take on his IBF, IBO and WBO counterpart in a unification fight at Hamburg's Imtech Arena and believes all he needs to secure victory is "a referee who can count to 10".
"I looked into (Klitschko's) eyes for 20 minutes and visualised me destroying him," he told Sky Sports News. "I looked into his eyes and saw him beaten and broken.
"He's never fought anyone with my attributes, it's new territory for me and for him.
"He'll do what he always does. I've fought these 'robots' before - I've never lost, at amateur or professional level, to an Eastern European fighter and that's not going to change now.
"He's got an impressive jab, I've seen him sicken people with it, but I don't believe the fight will go 12 rounds. Wladimir Klitschko's not tough enough, mentally or physically, no way - unless he gets a chin transplant, and with eight weeks I don't think there's time enough for that to heal!
"As soon as I let my hands go, the fight's over. I anticipate between 15,000 and 20,000 British fans coming over and they're going to see a knockout and a good show as well.
"July 2, I'm knocking out Wladimir Klitschko on his own turf - he's getting destroyed."
