Undefeated heavyweight contender Robert "Nordic Nightmare" Helenius (19-0, 11KOs) joined ATG Radio to discuss his career and the red hot heavyweight landscape. Helenius is picking his Sauerland Event stablemate Alexander Povetkin to pull off the upset and defeat WBO/IBO/WBA/IBF heavyweight champion Wladimir Klitschko on October 5th in Moscow, Russia. Helenius also shared that he sparred in the past with both David Haye and Tyson Fury, and picks Haye to come out on top on September 28th at the Manchester Arena.

"It's going to be two interesting fights. It hasn't been this interesting [in the heavyweight division] in a long time. I don't know what's going to happen. [If I had to pick a winner] then I would go with Povetkin and Haye," Helenius said.

"I have actually been a sparring partner with [Haye and Fury]. I was sparring with Haye before his Klitschko fight. I was sparring with Fury, I think long before the Chisora fight. I think Haye is more explosive but Tyson should keep his jab going and not let Haye come in. Fury is also a good fighter on the inside. I think Tyson showed heart in the Cunningham fight. He got knocked down in the second round and then he came back. I thought that showed heart and spirit and I found that cool about him. He showed his big heart in the fight."

"If Povetkin has been training really, really good - he has a chance. He has to go push the whole twelve rounds with full energy. He has a chance, but Klitschko is strong. If he lets Klitschko throw the jab all the time, then Povetkin is in trouble. I hope he has been training well, has had good sparring partners and he's really ready for this fight."
