Klitschko responds in war of words with Haye

Wladimir Klitschko has vowed to turned David Haye into "pizza face" when he defends his world heavyweight titles in Germany on June 20.

Klitschko's IBF, WBO and IBO belts will be on the line when the rivals clash before 60,000 to 70,000 spectators at FC Schalke's Veltins-Arena.

The giant Ukrainian has been repeatedly baited by Haye, who has completed his recent media duties wearing a T-shirt showing him carrying the severed heads of Wladimir and older brother Vitali.

However, Klitschko refuses to be riled by Haye's behaviour, which he views as "embarrassing" for the sport.

"David should have stayed at cruiserweight. He's only had two heavyweight fights but now wants to be champion," he said.

"He's been very provocative. He cut my head off for one magazine - that's pretty provocative so I decided to fight this boy.

"Now I see Haye with a cut off head of my brother, my family member. What's going to be next? My dad's head? My mother's head?

"Will he attack my religion, my race? This is over the edge - it's not sport. This guy will be punished.

"After 12 rounds he will be a pizza face - then I will knock him out. He needs to be taught how to behave.

"I don't want to waste my energy on this trash talk. It's embarrassing for the sport. He's a loser and I want to shut his mouth."

All three of Klitschko's defeats have been inflicted inside the distance, pointing to a vulnerable chin that Haye hopes to exploit.

But the 33-year-old has also knocked out 46 of his 52 victims, while the vastly less experienced Haye has ended 21 of his 22 wins early.

"I know as soon as my hands start connecting with his skull it's over," said Haye.

"I punch too hard, I'm too fast and that 'Bitchko' jab won't affect me.

"He's bigger and heavier than me and he's had more knockouts than I've had fights but all that will just make it more impressive when I beat him.

"He doesn't go to war like a true heavyweight champion should."
