Sam Allardyce has pledged to reinvest any money made from the departure of West Ham's star men this summer in order to build a side capable of returning to the Barclays Premier League at the first time of asking.
Although the Hammers boss does not want to sell the likes of Scott Parker, Robert Green and Carlton Cole, he knows the club's hand may be forced should sufficient offers come in.
Owners David Sullivan and David Gold have already demonstrated some resolve by rejecting a bid of £3 million from Stoke for Cole, while a price-tag of £10 million has reportedly been set for Parker.
And, should the Hammers be forced to cash-in on their prize assets, then Allardyce has assured fans it will only enhance his transfer kitty.
"If we sell, we will use some of that money to buy, there's no doubt about that," said Big Sam.
"We have lost £40m of revenue. A lot of the finance will have to be stumped up by the owners to get us back into the Premier League."
Meanwhile, young defender Jordan Spence has agreed a new deal to stay at Upton Park, with Zavon Hines and Jack Collison seemingly set to follow suit.
