Wladimir Klitschko's best undefeated opponent win?

[BWC]

I'm saying Pulev because Povetkin was so terrible against him. If he'd beat the Povetkin who's looked so monstrous in his last couple of fights I'd regard that win more highly.

Povetkin could never beat Wlad the way he beat Perez for example. Wlad is so much bigger, taller, reachier, and better than those guys it's not even funny. Wlad-Povetkin 1 is probably about as good as it's going to get between the two. This ain't Ali-Frazier folks..
