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.
