HAMBURG, Germany -- WBA champion David Haye promises a "brutal execution" of Wladimir Klitschko in their heavyweight fight Saturday.
Calling the IBF and WBO champion a "robot" stuck in his "rigid ways," Haye said he was in the best shape of his life and vowed to send the younger Klitschko brother to hospital in their bout in Hamburg's soccer stadium.
"You are going to see the most brutal execution of a boxer," Haye said Monday. "I will absolutely destroy him."
Speaking at the same news conference, Klitschko said he respects Haye as a fighter but not as a person.
"You have a certain attitude that is not so good for your life inside and outside the ring," the Ukrainian IBF and WBO champion said.
Klitschko (55-3, 49 KOs) promised to make Haye eat the T-shirt the Briton once wore depicting the image of himself holding the severed heads of the Klitschko brothers. Vitali, the elder brother, is the WBC champion.
Klitschko, who holds a doctorate in sports science, also said he believes he is the man to deliver the therapeutic defeat he thinks Haye needs to become a "better person."
"My name is Dr. Klitschko. I am a therapist and on July 2 I am going to give you treatment. It is going to be reality rehab. I will knock you out into reality, which will be good for your life," he said.
"You will be a better person and have better manners," Klitschko said.
Haye kept the news conference waiting for about 45 minutes before appearing in sunglasses and a T-shirt promising a KO in Saturday's fight, which had been 2½ years in the making.
"Be on time, princess," Klitschko admonished Haye.
Klitschko questioned why Haye would not shake his hand. Haye said he would do it when he visits Klitschko in the hospital after the fight.
The Ukrainian also wondered why Haye did not like to share a room with him. "Look in the mirror," Haye said.
Klitschko acknowledged that Haye looked fit and confident.
"I am going to get challenged in the ring," said Klitschko, while adding that he planned to punish Haye for 12 rounds before knocking him out toward the end.
Haye depicted Klitschko as a one-dimensional fighter.
"Wladimir is in great shape, is mentally prepared and has viewed all the tapes on me. But come fight night you will see something completely different and it will be great to watch this robot malfunction," said Haye, who is 25-1 with 23 knockouts.
"I am ready to do what I always promised I would do. I am healthy, the speed is ridiculous, the punch power is there. I am in a really good place. I am so happy the fight is happening now and not a couple of years ago as I am a much better fighter now," Haye added. "He is stuck in his rigid ways and has been since the amateurs."
