If this fight is really happening, it is a flat out joke. K2 is terrible. They must not want any credible challengers. They let none of them mature and they pick the very least worthy guys to stifle the others from being willing to mix it up. K2 is their own worst enemy.
I don't have any issue with Chisora... but his style IMO is a nightmare for Wlad... But Heaven for Vitali...
