Speaking with The Guardian, former heavyweight champion David Haye didn't sound too interested in a possible fight with WBC champion Vitali Klitschko, who defends his title against Tomasz Adamek on September 10 in Poland. Last Saturday in Hamburg, Haye lost a twelve round decision in his unification with Wladimir Klitschko. The British boxer plans to retire on October 13th - unless Wladimir grants him a rematch opportunity. Wladimir, the WBA/IBO/WBO/IBF champion, has no interest in a rematch, but older brother Vitali is more than happy to fight Haye.

"I definitely want to stick to my retirement plans, but when some beats you, you feel gutted – I'm such a competitive person. I'm going to retire on 13 October but the only person I would break my retirement for his the guy who's beaten me: Wladimir Klitschko. I don't know [if I would fight Vitali]. I don't have a beef with his brother. It's Wladimir, Wladmir beat me," Haye said.
