Serious question, I've lost count
The Wlad/Haye fight in June 2009 that didn't happen due to Haye's back injury and Setanta's collapse
July 2009 Haye and Vitali was supposedly agreed on, until Vitali read in the media Haye was fighting Valuev
What next?
2009 there were 3 negotiations. 2 with Wlad, 1 with Vitaly. Gayevid was slated to fight in Britain in March against Wlad but failed to deliver the stadium. Negotiations restarted again and were finally made for June in Germany. Gayevid faked a back injury with two weeks to go and pulled out of the fight. He has yet to provide proof of that injury. Wlad was pissed because he wasted the March date for another fight. The Gayevid told everyone that the Vitaly fight was a done deal and the day before signing announced that he will fight Valuev, turns out he was negotiating secretly behind Vitaly's back all that time.
2010 Gayevid hid from the Klitschkos for most of the year. Wlad called him out on YT in March, Gayevid stayed quite until September/early October, when both Kltischkos were officially signed to fight Briggs and Peter. He came out with his own video a week later after the last Klitschko (Vitaly) was signed to fight someone else saying: "The reason I have been quite all this time was because my mother always told me that if you don't have anything nice to say then don't say anything at all." (LOL @ that). The at the end of the year they began negotiations again after the Chisora fight was cancelled.
2011 Gayevid walks out of negotiations against Wlad. Says he no longer wants Vitaly even though they previously said the WBC was the most prestigious belt.
So officially, 4 pull-outs by Gayevid over 3 years. Really shameless that cunt.
