WBC heavyweight champion Vitali Klitschko has not ruled out fighting David Haye before he finally calls time on his illustrious boxing career.

The 42-year-old, who is considering a move into politics and running in the Ukrainian presidential election, has not fought for more than 12 months and any future bout would have to be sanctioned by the WBC.

Britain's Haye retired in October 2011 after a defeat by Klitschko's younger brother Wladimir, before reversing his decision in order to meet Dereck Chisora in July last year, and will take on Tyson Fury in Manchester at the end of September. Vitali's mandatory is Bermane Stiverne of Canada.

Klitschko expects to get back in the ring for what could well be a final contest and would have no qualms about taking on Haye.

Speaking to BBC Radio Five Live's Sportsweek programme, Klitschko said: "I think I will box again.

"My brother showed David Haye a very good fight, with a very good result.

"Let's see. Why not? But at the moment, I don't want to talk about major plans.

"I have an official contender (to fight in Stiverne), everything depends on the World Boxing Council."

Klitschko, though, stressed: "We are talking about things which are just speculations, right now there is no more information."
