Dereck Chisora has been bound and determined to get under Vitali Klitschko's skin. Vitali's brother, Wladmir Klitschko, is soaked with the collateral damage of these efforts. 

Moments before Chisora was to begin his fight with Vitali, he went face-to-face with the other Klitschko champion, Wladmir. 

The two spent a few moments giving each other the stare-down treatment. Then the British challenger decided to add a new twist to the stare-down routine: He let out a massive spit that was a direct hit in Wladimir's face. 

And it was massive. I don't know if Chisora had some water resting in his mouth for this moment, but the quantity borderlines on the edges of human possibilities. 

Maybe he just wanted to prove he was salivating at a chance to fight for the belt. A chance he was twice denied by Wladimir.

Twice Chisora and the younger Klitschko had been scheduled to fight and both times Wladimir had to pull out due to injury. So, maybe this disgusting gesture was a token of Chisora's frustration. 

More likely, it was just a continuance of the bravado Del Boy is trying hard to display leading up to this fight. 

Chisora likes to use stare-downs for these displays. At the weigh-in, while he and Vitali were locked in a stare-down, Chisora unexpectedly slapped Vitali.

Through it all, the Klitschkos have remained fairly stoic. If Chisora's attempt to get under the skin of Vitali is working, the champ is certainly doing a fine job of hiding.
