The champion of the WBO/IBF/IBO, Wladimir Klitschko says there is no justification for David Haye to avoid their fight. In an interview with Today, Klitschko said the fight would happen in the fall, between September to November and there will be a rematch clause in the contract. The fight appears to be taking place in Germany, but Klitschko does not rule out the chance of fighting in England.

The fight will lead Klitschko on the road to fight IBF mandatory contender Alexander Povetkin. The IBF has given Klitschko additional time to make a unification fight with Haye, the WBA champion.

"The IBF has given us still some time to complete negotiations. A purse bid [for Alexander] can only be ordered once the situation with Haye is finished. We have a couple of weeks to negotiate with him and either we'll agree or we won't agree," Klitschko said.

"Unifying the titles is always a priority for any of the boxing organizations. It is written in their rules. They gave me the green light, and Haye got the green light. Haye has permission to make a voluntary defense. This time there is nothing to prevent Haye from fighting me."
