Personally I don't see either man beating Wladimir. Povetkin might be able to give him some competitive rounds early before he eventually gets caught. Peter on the other hand has declined dramatically since his fight with Wlad. Aside from the knockdowns in their fight Peter was pretty much dominated.

I favor Povetkin over Peter if they fight. I think his shorter, crisper punches(particularly hooks) will be the difference maker.
