Povetkin: I became stronger than before the Klitschko fight

"I'm in very good shape, I had a good training camp, Joshua is one of the strongest heavyweights in the world, I'm happy that I have the opportunity to go out with him in the ring and give the fans a good fight. Anthony is a strong fighter, but I'm just as strong. When I fought Klitschko, I was much weaker and was in poorer condition than now," Povetkin said.
