West Ham insist they will not break the bank to retain star keeper Rob Green and captain Matthew Upson.
The duo have 18 months left on their existing Upton Park deals and both are yet to agree on extended terms.
Hammers' new co-owners David Gold and David Sullivan have already hinted the pair could be sold in the summer unless they sign extended contracts.
Gold insists their immediate priority was to strengthen in order to maintain their top flight status, having brought in the likes of Mido, Benni McCarthy and Brazilian forward Ilan before the window closed.
West Ham's hierarchy will now sit down and look at contract proposals, however, Gold insists West Ham will not be dishing out lucrative deals that they cannot afford.
"Our priority was to work hard until the transfer window closed," Gold told the Daily Star.
"We wanted to get a few players in. Now we've done that we have to ensure Premier League survival.
"We can now sit down and look at players' contracts. With regards to Upson and Green, it depends on our finances.
"We will do everything we can to retain our best players, but at the same time we can't spend money we don't have."
