Bernd Boente, regarded as the man behind the Klitschko brothers' success, has admitted he was impressed by the Englishman's victory over Dereck Chisora last weekend; his first outing since a comprehensive points defeat to Wladimir Klitschko last July.
Haye has stated he would like to face Vitali next after a proposed clash with the WBC Champion on September 8 fell through, but the Ukranian is now set to face Manuel Charr on that date and may then hang up his gloves to pursue a career in politics.
However, Boente told Ringside he would not rule out the possibility of a clash at some stage.
"I can't foresee the future," he said. "We have to wait and see for September 8 and then the elections, but down the road let's see.
"It could be Vitali, it could be Wladimir some time next year. At this moment, promotion-wise, I think that fight makes no sense after one year, but let's see. David is definitely a flashy person, a personality and he is always in the media, so why not?
"We are all in an entertainment business and I'm sure that the Vitali versus David fight would be a thrilling fight, an interesting fight and would definitely be the fight the boxing world wants to see."
Vitali has stated he would like to finish the job his brother started by knocking out Haye, who once famously wore a T-shirt depicting himself carrying the severed heads of the Ukrainians.
And Boente feels that another Haye-Klitschko showdown would be prove to be one of the biggest tickets in boxing.
"Without any doubt," he added. "I would not even rule out a rematch between Wladimir and David down the road, but at this moment it makes no sense because Wladimir's win was clear.
"There were no question marks at all, but Vitali's fight against David would be by far one of the biggest fights in boxing, not only in the heavyweight division."
