Alistair Overeem has made the staggering revelation that he may quit MMA after the Strikeforce Heavyweight Grand Prix, in order to fight boxing champion Vitali Klitschko.

Overeem is the reigning Strikeforce heavyweight king, and he is heading for a semi-final in the Grand Prix against Antonio Silva. If he wins the entire tournament, he is expected to be chased by the UFC to take on the likes of Junior Dos Santos and Cain Velasquez in what would be deemed 'super-fights'.

However, Overeem may have other ideas. Having extended his unbeaten streak to 10 fights, it seems the K-1 World Grand Prix champion may take his kickboxing background and apply it to boxing.

Vitali Klitschko is currently without a genuine rival after he and brother Wladimir unified the heavyweight titles. A clash with David Haye, recently defeated by Wladimir, has been mooted for Vitali, but Overeem is eyeing an opportunity.

"I might go to UFC or boxing," Overeem was quoted as saying by MMA Mania. "Definitely, [I'm seriously thinking about fighting Vitali Klitschko]. I think it matches my personality.

"I'm always looking for a challenge. That came about in fighting for K-1 and becoming K-1 champion, something nobody ever did before. It would be cool to go to boxing and beat the main guy there.

"If you give me a good preparation, good sparring partners, which I can arrange, I can fix that, with my background already in kickboxing, my K-1 background, I'm sure I can break some bones."
