Vitali Klitschko is "very jealous" of little brother Wladimir after his sibling won their fight to take on bitter rival David Haye this weekend.

Outspoken Englishman Haye has spent nearly three years goading the Ukrainian champions in an attempt to lure them into the ring.

After much trash-talking and protracted negotiations he will finally get his wish on Saturday when he risks his WBA heavyweight title in a unification bout with IBF/WBO champion Wladimir in Hamburg.

Vitali, however, admitted he is "very upset" at being denied the chance to punish Haye for his unsportsmanlike conduct, which has included him wearing a t-shirt depicting the decapitated brothers.

The older Klitschko, who holds the WBC title, said: "I am very jealous of my brother.

"I told (Adam) Booth, Haye's manager, 'after my brother beats David, I have nothing to do!'.

"Some people are talking and saying I'll be the next one to fight him but after Wladimir is finished, I have nothing to do with David Haye.

"I'm very upset because my brother took David Haye away from me. I want to fight him.

"If you asked me to fight David Haye after Wladimir ... there's no interest in it. There is no point fighting him.

"I am jealous of Wladimir but you know what? There was a big fight between me and my brother over who fought David Haye. Haye made the choice, to fight the younger brother.

"I am upset but I will support my brother and I know that it is a Klitschko against David Haye. It will not be an easy fight but the Klitschko will win.

"The important thing is that we hold all of the heavyweight titles in the Klitschko family. It's a great challenge for us."

Unsurprisingly Vitali, 39, is tipping his 35-year-old brother to win but stopped short of predicting a landslide.

"It will be a big battle," he said. "As a boxer and an expert I am very excited. I know it won't be an easy fight for my brother.

"Both fighters have a great chance to be the best in the world and that's why I expect a great fight.

"Wladimir trusts himself. He is not angry or emotional. David Haye is emotional, trying to provoke my brother, but he has been unsuccessful.

"Let's see. We have a bit more time until the fight and the psychological fight starts now. Who will fare better? We'll see on Saturday night."
