what was Wladimir's best performance?

[Jimanuel Boogustus]

I think I'd have to say Haye.

Most 'threats' tend to deteriorate fairly quickly against WK but against Haye, WK faced a guy who was equally as athletic and as equally threatening and boxed immaculately for twelve rounds.

If you're not convinced then consider the fact that according to Haye, a stand up European boxer presents the best style match for him to land his Hayemaker and yet he was beaten so convincingly by it.
