Povetkin’s Coach: The strongest rival in Alexander's career was Klitschko

Ivan Kirpa the coach of Alexander Povetkin said that in the career of the Russian heavyweight the most powerful opponent in terms of the art of boxing and status was Wladimir of Ukraine.

The fight was staged in October 2013 in Moscow. Klitschko got the victory by unanimous decision.

"I think that Wladimir Klitschko was Alexander's strongest opponent at the moment in terms of the art of boxing and status. Briton Anthony Joshua, of course, does not yet have such a rating and such fame that Wladimir had," Kirpa said.
