"It's in their hands. As far as I am concerned all the points have been agreed verbally, but subsequently Vitali came out and said the fight was 'miles away' from being made. I don't understand why he would say that. Maybe they are just using David's name just to get some publicity."
Booth and Haye have enjoyed a colourful relationship with the Klitschkos and their management since the Briton moved up to the heavyweight division in 2008.
Haye courted controversy by getting a T-shirt printed depicting him holding up the decapitated heads of both brothers and then caused more uproar by launching a mobile phone application which showed him knocking the head off "an eastern European" fighter that looked very similar to the Klitschkos.
Booth has also clashed with the Klitschkos' representatives in the past and is not surprised negotiations are dragging having experienced similar problems before.
"Until they send the contract and until it is signed, I will try not to waste too much time on it because you have to remember, I have negotiated with them four times now and there has only been one fight," Booth added.
"They probably say the same about us, but they are the hardest people I have ever dealt with."
Vitali has opted to defend his crown against Dereck Chisora in Munich next month despite the unfancied Londoner losing his last two fights while Wladimir takes on Haye victim Jean-Marc Mormeck a fortnight later in Düsseldorf.
Booth reckons neither Klitschko has any chance of losing their next fight and attacked the brothers' choice of opponent.
"Wladimir has to get through the Chisora fight, but he won't struggle against him. Neither will Wladimir against Mormeck," Booth said.
"David knocked Mormeck out in seven rounds and he was a blown up light-heavy moving in to cruiserweight. He was past his prime then.
"Now he is a blown up light-heavy who is a few years past his prime. If they are happy fighting people like that then good luck to them.
"These guys are three stone heavier and five inches taller than their opponents and they expect to be lauded as all time greats, but I don't buy it.
"Any fighter who fought someone who was three stone lighter and fives inches smaller, and they didn't deal with them easily would be kicking themselves.
"They would be disgusted with themselves. They wouldn't be lauding themselves."
