Chelsea chairman Bruce Buck has insisted owner Roman Abramovich does not stand to gain financially from any possible stadium move.
The Blues last week made an offer to buy back the parts of Stamford Bridge sold to supporters in the 1990s in what has been seen as a precursor to a move to a new 60,000-seater ground.
"To build a new stadium of 55,000 to 60,000 seats would cost in the region of Â£450million which with the land, would total maybe Â£500m to Â£550m," Buck told Chelsea TV. "The profit on the redevelopment of Stamford Bridge would be maybe a third of that amount, and money from other sources such as Mr Abramovich and banks would be needed to move to another location."
He added: "The profits would be an important component of the funds should we would need them so it would not be possible to do it without taking that redevelopment money. There is no possibility for Mr Abramovich to make any money."
He continued: "I don't know how much money Mr Abramovich has.
"He has invested Â£800m into this club, and no matter how much he has he must notice he has invested Â£800m. A figure of Â£500m for a new stadium is a lot of money no matter who you are, and the decision has been made that we're not going to move to another stadium unless we can take the proceeds of a redevelopment of Stamford Bridge towards it."
Buck claimed the views of Chelsea fans would be taken into account when deciding the site of a potential new stadium.
"You have to respect the fact that Mr Abramovich is a Chelsea fan and it would not make sense to move the stadium to somewhere that was not to the satisfaction of the bulk of Chelsea fans," he said.
