Wladimir Klitschko stands to earn almost US$17 million if he beats Francesco Pianeta in Mannheim, Germany, on Saturday night.If the Ukrainian wins against Pianeta, a cancer survivor, he could fight Russian heavyweight Alexander Povetkin in Moscow’s Olympic Hall on August 31.A Russian promoter has already won the purse bid to stage that bout. Vladimir Hryunov bid $23.33 million. As WBA "super” champion, Klitschko could get 75 per cent of the amount, adding up to $17, 250 000; more than he has ever received for a fight.Povetkin is the WBA "regular” champion.

"It is the opportunity of a lifetime for him and he has already won his toughest fight, because he has defeated cancer.”Klitschko wants a quick knock-out. "I will give everything for a clear win,” he said.Klitschko and Povetkin, both former Olympic Games champions, were due to clash twice before but Povetkin pulled out in 2008 because of an injury and then backed out a second time in 2010.
