Wladimir Klitschko is one of heavyweight boxing's biggest names, previously holding the WBA, WBO, IBF and IBO World Heavyweight titles before losing them to Brit Tyson Fury. The seasoned fighter has won over sixty fights, and over fifty of them by knockout.
He has been rated as the number two pound-for-pound fighter in the world, the second longest reigning heavyweight champion ever after Joe Louis, and he has the second most successful title defences of any heavyweight boxer, ahead of Muhammad Ali.
Klitschko shares his legendary status in heavyweight boxing with his retired older brother, Vitali Klitschko. When his brother stopped fighting, he held the second best ever knockout-to-fight ratio of any heavyweight boxer and was never knocked down in a professional bout.
Klitschko has a PhD in Sports Science, awarded by Kiev University of Physical Science and Sports. The fighter is also an avid chess player and golfer.
Klitschko has won recognition for his involvement in humanitarian projects alongside his brother, helping disadvantaged children in Africa and South America. He was named curator of the Ukrainian pavilion at the 2009 Venice Biennale.
The old one-two
Klitschko's style incorporates a highly skilled use of the left jab, with minimal elbow flare, reminiscent of Larry Holmes. The Ukrainian stands side-on to his opponent, half extending his left hand and using it to keep the other fighter at distance, peppering the jab and probing for bigger shots.
Examples of Klitschko's impressive style and use of his size can be seen in his 2008 victory over Hasim Rahman and 2011 victory over David Haye.
Klitschko's first world title
Kiev's crusher won the WBO World Heavyweight Championship in 2000 by unanimous decision against Chris Byrd, who had seized the title from his brother, Vitali. By this point Wladimir Klitschko already had a record of 35-1, an amazing amount of fights to rack up in just four years of being a pro.
Since then he has had a dramatic journey that includes losing the WBO World Championship to Corrie Sanders in 2003 and failing to reclaim the vacant title against Lamon Brewster in 2004. But after these set-backs, the Ukrainian giant has subsequently won all of his fights.
By the time Klitschko won back the WBO world title from southpaw Sultan Ibragimov in 2008, he had claimed the IBF and IBO World Heavyweight Championships.
The fight seemed uneventful but was in fact a masterclass by Klitschko, who hurt an overwhelmed Ibragimov throughout with his unrelenting jab.
Klitschko v Jennings
In April 2015, the Ukrainian powerhouse fended off unbeaten Bryant Jennings to pen in his 18th consecutive world title defence. Although he scored a relatively comfortable unanimous decision, Jennings was able to cause Klitschko a few problems with his movement.
A loss against Tyson Fury, and the rematch
In November 2015, Klitschko suffered a shock defeat in Dusseldorf against outspoken Manchester fighter Tyson Fury. The Ukrainian lost his quartet of Heavyweight World Titles in the process.
Unfortunately the rematch, which was originally lined up for July and then October has since been called off due to injury.
