Klitschko goads Lewis

Lennox Lewis was today challenged by world heavyweight champion Vitali Klitschko to come out of retirement and complete some unfinished business.

Now, ahead of a first defence of the WBC title against Danny Williams in Las Vegas on Saturday week, Klitschko said to Lewis: "I beat you the first time and I'm more than sure I will beat you a second time."

In Los Angeles 17 months ago, Lewis was trailing Klitschko on all three judges' cards before deep cuts around the Ukrainian's left eye proved too severe for him to continue at the end of the sixth round.
