Vitali Klitschko beat Shannon Briggs in October in his last bout

Vitali Klitschko says he wants to sign a contract with David Haye to fight in spring 2011 within "the next month".

Haye retained his WBA heavyweight title when he demolished Audley Harrison, while Klitschko is the WBC champion.

Klitschko is the older brother of IBF and WBO champion Wladimir and wants to fight Haye first because "Wladimir will kill him".

Vitali Klitschko told the BBC: "Stop talking. I'm ready to sign any time, let's make the fight in springtime."

He continued on BBC Radio 5 live: "No excuses any more, he talks too much, he's a great talker, but the question is, is he a good fighter or not?

"Let's make contract. Straightaway we are ready to sign the contract - I want to fight David Haye."
