Underrated heavyweight champion Wladimir Klitschko presents big test for world title challenger Alexander Povetkin Yet Klitschko, underrated by constant detractors, is actually the longest-serving heavyweight champion since Detroit's Joe Louis, who reigned between 1937 and 1949. The Brown Bomber is considered perhaps the greatest heavyweight ever. In time, regardless of the opposition, and as history fades the sharp memories of this era, Klitschko, too, is quite likely to be considered amongst the best. He has been involved in 23 world title fights since his amateur peak at the Atlanta Games in 1996, where he won Olympic gold. Not unlike his industrial sponsors, though, Klitschko offers little in the way of frills and fancy. The antidote to the belligerent lip of Tyson Fury, or David Haye, come to that. And we know what happened when the Londoner and the Ukrainian took the ring. Different levels. It really was super heavyweight against little heavyweight. Haye has speed to spare in the heavyweight division, yet Klitschko controlled the distance with ease. That's why the anticipation for the matchup between Ukraine and Russia has barely ignited outside Eastern Europe, in spite of a £21 million purse for this fight, as the official WBA, IBF, WBO, IBO heavyweight champion of the world defends his titles, with a record of 60 victories from his 63 fights. With elder brother Vitali holding the WBC crown, they are the first siblings to unify all heavyweight belts under one family name. Klitschko tends not to engage, but dictates the pace through his clever two-step, half-step, in out movement. Povetkin's chance will to be exploit the champion's unwillingness to engage, and fear of being caught on the chin, yet if Klitschko keeps to a script that has seen him unbeaten in 18 fights since 2004, he will force the Russian to eat jabs until he comes forward no more. This is the best fight in the heavyweight division right now. As an amateur Alexander Povetkin was a world and Olympic champion, he has not lost a fight in his career and has never been on the canvas," said Klitschko. He is the best opponent I've ever had. I am truly delighted about the support of such a strong international business player as Interpipe, which represents my native country all over the world. Interpipe, like Klitschko, does what it says on the tin. Stands strong. Delivers. Expect Klitschko to walk away with the spoils, and a giant suitcase of roubles from Russia. Klitschko v Povetkin is live and exclusive on BoxNation (Sky Ch 437/Virgin Ch 546) on Saturday Oct 5th from 8pm.
