Wladimir Klitschko defended his WBO and IBF titles with a comfortable win over American Tony Thompson on Saturday.

Thompson, 36, had a promising opening round but the 6ft 6in Klitschko quickly seized control, despite suffering a cut to his eye in the early rounds.

The champion's power wore down Thompson as the fight progressed, with Klitschko easily outboxing his tiring rival.

But the Ukrainian struggled to put away his opponent before finally ending his misery in Hamburg after 11 rounds.

Klitschko will have done little with his showing to put any fear into his rivals in the weight division.
