Who can beat Wlad???

Honestly none of the guys you listed ..David Haye may be the most popular out the buch but his jaw will get cracked once Wlad gets his hands on him !

 

Besides Vitali I reckon Tua - he's the only guy on that list that's used to giving up so much height and reach to an opponent, also I dont think Wlad will be able to do what no-one else could and knock Tua out. Tua's got the power, and knows how to slip a jab.
That said, right now, Wlad has to be a massive favourite going into a fight with anyone who's last name isn't also Klitschko
