( CNN ) -- Boxing world champion Wladimir Klitschko has told CNN that David Haye will become the 50th knockout victim of his career when the two face-off in July . The IBF , IBO and WBO heavyweight champion is set to face WBA champ Haye in Hamburg , Germany , on July 2 in a bid to unify four of the division 's five belts . The Ukrainian recently pulled out of his scheduled April 30 fight with another British boxer , Derek Chisora , and boasts a formidable record during his 15-year career , winning 55 of his 58 fights -- 49 coming via knockout . And he claims Haye is the perfect man to help him notch up a landmark half century . He told CNN : `` I knocked out 49 fighters and David Haye is going to be the 50th on my list . I am looking forward to it , I will get a great challenge in the ring . `` He will try to get through with his strategy , psychological and physical game and I 'm ready for it because I 'm a true professional athlete and have been doing it for such a long time . I love to be challenged . '' Londoner Haye can also point to an impressive record in the sport , having won 25 of his 26 fights , 23 coming via knockout . The 30-year-old moved up from the Cruiserweight division in 2008 and has made public his desire to fight Wladimir , and his older brother , the WBC heavyweight champion Vitali , before he retires on his birthday -- October 13 this year . When Wladimir was asked what would happen if Haye was to win their July bout , he replied : `` ( Defeat ) is not an option -- myself and Vitali are going to unify all the belts . `` Haye is quick and his record speaks for itself . He won a lot of fights by knockout , so I will not underestimate his speed or his punching power . `` I 've been in boxing for last 15 years and I 'm going to be close to 60 fights , I know exactly what to expect from every single opponent . '' Wladimir also denied that he will enjoy any advantage from the fact that the contest will be staged in Germany -- the country that has hosted many of his title fights in the past . He explained : `` It 's not really an advantage because the ring is the same everywhere -- it has four corners with a referee in between you and your opponent . `` It 's all about the way you fight and how you follow through with your plan and tactics . ''
