I know the Klits would never fight and don't expect it or want to see it, but does anyone know if there's any footage of them sparring anywhere? It'd be interesting to see, that's assuming they do spar together.

Not getting my hopes up too much on the Haye fight, but I think the most solid sign that it'll happen is here
"We are now perfectly positioned to get together and make this fight with Wladimir Klitschko. "Despite the fact we know we bring more UK television money to the table, David and I are happy to split the entire pot 50-50 and grant Wladimir the deal he has wanted since day one.
"We have offered them 50-50 on everything - just as they requested - and now see no reason why this tremendous fight can't happen. The path is clear." from Adam Booth.
In that quote too it clearly says it's been the Haye camp holding up over the TV money, as we suspected.
Seems promising, as long as the extra money that's been mentioned doesn't become a factor. This clearly should be complete 50/50, and Booth and Haye should know it.
