Bernd Boente, manager of WBC heavyweight champion Vitali Klitschko, disputes a Twitter announcement by British heavyweight David Haye, who claims Vitali agreed to fight him next. The two sides were trying to negotiate a fight earlier this year, but Klitschko walked away from the table.

Boente, currently at a post-fight press conference in Düsseldorf for Wladimir Klitschko's knockout victory over Jean Marc Mormeck, told BoxingScene.com that Haye announcement is simply "not true."

According to Boente, Haye is a demanding a "ridiculous guarantee" and "50% of the British pay-per-view" - demands which the Klitschko side is not willing to accommodate.

Haye rejected Klitschko's offer in December - but the door is still open, says Boente, for Haye to return to the table and accept the offer that was previously rejected - or the Klitschko side will move forward with another opponent.
