Despite not being a fan, I like how humble and straight-talking Vitali is. He's always going to have opponents that chat shit in front of him and make funny gestures, but he just maintains his composure and smiles in that funny way.
I could never hate or even dislike the Klit brothers, whether or not they face/defeat/lose to Haye. They're the gentlemen of the sport, and have great skills to back it up.
