Former heavyweight champion, 48-year-old Briton Lennox Lewis, arrived in Moscow, Russia for Saturday's major battle between WBA, IBF, IBO and WBO heavyweight champion Wladimir Klitschko of Ukraine and undefeated mandatory challenger Alexander Povetkin of Russia. The fight is staking place at Olympic Stadium. Lennox is very familiar with Povetkin and gives him a good possibility to pull off an upset victory.

"I have seen a couple of [Povetkin's] fights, and I can say that he is a rising star - he's strong and he's still a young boxer. With Klitschko, Povetkin will have to fight him close. I do not think the fight will last 12 rounds. If the fight drags on, then Klitschko will win and if there is a knock-out in the beginning of the fight, Povetkin will get the win. This fight is going to be tough and spectacular. Povetkin is fighting against the super champion of the world, who held the titles for a long time, who is taller and heavier. Alexander has a great punch and that can save him in this bout. I can say this - Povetkin has a powerful shot and if he properly catches Klitschko, the Ukrainian will fall," Lewis said.
