Bernd Boente, manager of WBC heavyweight champion Vitali Klitschko (43-2, 40KOs), has denied circulated reports that he offered David Haye (25-2, 23KOs) additional time to accept an offer to fight his boxer in the summer.

The problem, as previously reported, is money. Haye is requesting a "huge guarantee" to fight Vitali, but Boente believes there is too much financial risk to meet that number - because the British public is still steaming over Haye's in-ring performance with younger brother Wladimir Klitschko from last July. Even Haye admits his performance against Wladimir was lackluster, but his post-fight excuse of an "injured toe" was the kicker which sent the paying public into a fury.

Haye announced his retirement from boxing in October, but says he's willing to return for Vitali.

Vitali returns this coming Saturday night in Munich, defending his title against former British champion Dereck Chisora (15-2, 9KOs).

"We made an offer two weeks ago and he turned it down. We are not even negotiating anymore. He wants a huge guarantee and there is too much risk. We don't know how the British pay-per-view will do because Haye is not a superstar anymore because of his performance with Wladimir. As of right now the fight is off. Knock on wood that Vitali beats Chisora on Saturday night, we will start negotiating with some opponents but it won't be David Haye," Boente told BoxingScene.com.
