He's a modern day Primo Carnera, a circus act. He isn't meant to be a top level boxer. Chagaev will beat him again.
The WBA would rather have an interim belt holder in the human freak show than have a 46 yr old, over-the-hill fighter. They'd rather turn boxing into a circus show than stay to its martial tradition. It's all about the money and advertizational leverage, and the WBA is the shittiest of all alphabets anyway. I'd say boycott WBA!
Valuev looked in worse shape than usual for this fight - if that is even possible! It looked like he had gone 12 rounds with McDonalds...and lost! What a joke!
