Bernd Boente, manager of the WBC world heavyweight champion and his brother Wladimir, insists Vitali will take his time over deciding whether to retire.
The 41-year-old's UDAR party was elected into the Ukrainian parliament with 13% of the vote and now the wrangling over the formation of an opposition coalition begins.
"Vitali will not make a decision before December or the beginning of next year," Boente said.
"He's under no pressure. The WBC see him as their champion and he only had a fight at the beginning of September. No champion will fight twice in three months.
"Whether Vitali fights on depends on the political situation and the coalitions formed.
"His party was only founded two years ago but it received 13% of the vote. He's in parliament now as the party leader.
"We will have a clearer picture of the political landscape in mid-December and after that Vitali will make a decision."
Boente describes a report that the Ukrainian brothers have signed a five-fight deal with RTL, Germany's largest private free-to-air broadcaster, as premature.
It was reported that the fact the contract was split between Wladimir - the IBF, WBA and WBO champion - and Vitali indicated the latter's determination to box on.
But Boente said: "The deal has not been signed yet. We are in negotiations and it should work out well.
"We've inserted a general clause that it will be either brother, which we've always had.
"Should Vitali retire, Wladimir is the only guy involved. If Vitali fights on then he will take a portion of those fights."
Haye has declared the only fight he will accept is against Vitali, having dropped a wide points decision to Wladimir in July last year.
Boente insists Vitali has no interest in facing Haye, yet it is the most attractive - and lucrative - fight in the heavyweight division.
Due to the one-sided nature of their first showdown there is no mileage in a return against Wladimir, but his fading and worn older brother is an easier prospect.
Boente remains dismissive of Haye, who has refused to meet rising British heavyweights David Price and Tyson Fury, but the fight would an easy sell.
"It's always the same with Haye, we don't take him seriously. He's a like a little dog that barks all the time," he said.
"When the big dog - Vitali Klitschko - comes around the corner he runs away.
"Look at what happened against Wladimir, we don't care about it him any more. He talks but who cares?"
