Doubt I'll see it as on a bit of an all dayer Saturday but it has the potential to be half decent.
Everyone expects Vitali to punish him (and he probably will) however if Chisora comes in prepared and fit as he did against Helenius then he might just be able to make it interesting. However, if he comes in as he did against Fury then he gets banged out in a round!
Problem will be getting in behind Vitali's jab as Chisora is not particularly tall for a heavyweight and Vitali's jab is like a piston and he follows it up with the right cross very well. Chisora has speed and a decent dig so if he can test Vitali's chin it could be a cracker.
After saying all this though I think the smart money is on a UD for Vitali or a mid to late stoppage.
I do think that Delboy will put up a better fight than Haye did against the other brother though!
I just can't see how DelBoy will get past the jab. As you say it's piston like and Chisora just isn't mobile enough imo. I can't see this making it to the end.
I did read on another forum though that it has been 11 years since the last major heavyweight upset (Lewis/Rahman) and it was 11 years before that for the one before (Tyson/Douglas) so you never know!
