Wladimir Klitschko has insisted that he will make David Haye his 50th knock-out when the two meet in a unification bout on July 2 in Hamburg.
The IBF, IBO and WBO champion 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 34-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.
WBA champion 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.”
