Klitschko in no rush to quit
Wladimir Klitschko claims he plans to stretch his boxing career for another decade in his bid to break the record of Joe Louis as the longest reigning world heavyweight champion.
The 38-year-old, who has been world champion since 2006, defends his WBA, IBF, WBO and IBO belts in Oberhausen, Germany, on Saturday against Australian challenger Alex Leapai.
US boxing legend Louis was world heavyweight champion for 12 years, having been unbeaten between 1937 and 1949.
In order to beat the record, the Ukrainian will have to remain unbeaten for the next four years when he will have celebrated his 42nd birthday.
"I just turned 38, but that's only a number," Klitschko said.
"I am still extremely hungry and better than ever. A few years ago, I thought I couldn't improve, but my mission is still a long way from over. I want to box on for ten more years.
"I feel the combination of experience, athletic-ability, technique and strategy makes me the complete professional."
Klitschko admits it has been challenging to prepare for his 65th professional fight with his brother Vitali in the thick of their country's volatile political situation in Kiev.
"It's a bizarre situation," Klitschko added. "My body has been training at the camp in Austria, but my mind is often with my brother and our compatriots in Ukraine."
