Wladimir Klitschko predicts quick KO in heavyweight title defense against Samuel Peter

Wladimir Klitschko is predicting a quick knockout in his rematch with Nigerian fighter Samuel Peter on Saturday.

Klitschko says he is a much better fighter than he was five years ago when he was sent to the canvas three times before beating Peter in a unanimous decision.

Peter is challenging the Ukrainian holder of the IBF, WBO and IBO heavyweight belts and is equally confident of a quick victory.

The Klitschko brothers remain a big draw in their adopted homeland of Germany and the fight at Frankfurt's soccer stadium is expected to draw 40,000.
