The BoxingScene.com website reported that "the venue has not been finalized and contracts will be signed by the end of the week."
'Dr. Steelhammer' Klitschko (52-3, 46 KOs) said he was glad the fight has been scheduled, as he was getting tired of "listening to trash talks" from Haye (22-1, 21 KOs).
"I am happy to have this fight. I have had a lot of opponents with big mouths, but I never had an opponent with such a big mouth like David Haye," the website reported quoting the 33-year-old as saying.
The 28-year-old Briton earlier accused Wladimir of only fighting cowards, and recently pledged to knock Klitschko out, and take his IBF and WBO belts home to London.
"None of the opponents I have had were as provocative as David Haye, so I am glad to shut his mouth by putting my fist in his mouth. There is no way this fight will go the whole distance. It's a signature fight for me and I am happy," Klitschko continued.
Haye also said earlier that after he was through with Wladimir, he would go after his older brother Vitali to get his WBC champion's belt.
In early December last year, Vitali 'Dr. Ironfist' Klitschko (37-2, 36 KOs) and Haye met at a restaurant in Germany, and Haye gave the Ukrainian a British edition of Men's Health magazine which had a photo of Haye posing with the decapitated head of Wladimir Klitschko.
Vitali lost control and grabbed Haye by the neck, and a minor scuffle took place.
Klitschko said later that he wanted to square off with Haye, who in turn told the BBC in an interview that he had reached a verbal agreement on a bout with Klitschko.
