Undefeated Dereck Chisora is tired of hearing David Haye's mouth. The WBA champion is upset with Wladimir Klitschko's decision to defend his WBO/IBO/IBF titles against Chisora on April 30 in Germany. Chisora has dared Haye to involve himself in a four man doubleheader, with Chisora facing Wladimir, and Haye fighting older brother, and WBC champion, Vitali Klitschko in the co-feature. Chisora told Haye to move forward with his plan to retire by October because the sport of boxing won't miss him.

Wladimir has offered to fight Haye on July 2, but the British champion is refusing to finalize the date until Klitschko scraps his plan to face Chisora in April.

"To make it more interesting, David Haye and me against the [Klitschko] brothers under one roof - that would sell," he told Sky Sports. "Then he [Haye] can retire because the boxing game isn't going to miss him, he hasn't given us any good fights. When was the last time you can remember when you could say, 'that was a good fight David'? If he goes, bon voyage."
