At 39, Klitschko still remains king of the heavyweight ring

Wladimir Klitschko looks around the boxing landscape and sees young heavyweights, lots of young heavyweights. At his age, 39, that is hardly unnatural.

What is unusual is that none of those youngsters - or any other opponent - has presented much of a challenge for his championship belts.

Klitschko has been on top for nearly a decade since taking the WBO crown from unbeaten Samuel Peter in 2005. He added the other alphabet titles during a string of wins that now has reached 19. Yes, many of them came against unimpressive opposition but that is hardly Klitschko's fault. If the rest of the heavyweight field is, well, lightweight, he just goes about his business of compiling victories.
