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."
Klitschko has promised he will make Haye his 50th knockout victim - and also claimed he agreed to give Haye equal terms to make sure the fight went ahead.
"Forty-nine fighters have been knocked out in the last 15 years and David Haye has completely disrespected them," he told Sky Sports News.
"I will show him that he is just going to be another like the 49 before, he will be number 50 on July 2 and that is the way it is going to be."
The 35-year-old Ukrainian added: "He has to have 50% which I dont think he deserves, so I gave in and gave 50% otherwise it wouldn't have happened."
Haye spent the majority of the press conference questioning the ability of his opponent, but Klitschko has moved to praise Haye's prowess in the ring.
He said: "I want to show respect to him, which may surprise you but he has certain qualities.
"He has heavy hands and great speed as well as being motivated and this time the steam came out of his ears because suddenly he has this anger and I think I will be challenged in the ring."
The Imtech Arena in Hamburg will host the fight but the British support for Haye is still expected to be strong and Klitschko has been impressed by their attitude.
"British fans are amazing because I have been to fights in the US where British fighters are involved and they are singing songs and really loud," he said.
Haye, 30, suggested Klitschko's confidence may prove to be misplaced.
"He's had a long run and if he's been reading his own press then maybe he is confident, maybe he does believe he is invincible," he said.
"I've lost a fight, the better man (Carl Thompson) won on the night. I've learnt from that and become a champion - he's lied about why he's lost, blaming it on someone drugging his water or putting a substance in his Vaseline.
"Someone looking for excuses is someone who's going to get knocked out. A referee that can count to 10 is all I require."
