Lets face it, these stupid belt aren't worth a damn now anyway. ITs all about the names on your resume, and I know either Klit would love to have Chagaev on theirs. Now that Chag has been locked out of the WBA picture, maybe he will lobby to be a defense for one of the Klits. Vitaly would make the most sense, as Wlad has some quality fights against Haye, Povetkin, and the winner of Dimintrenko-Chambers coming up.
The point is that Chagaev is still the only guy who officially beat Valuev, Wladimir can't become Ring Champion without beating him.
