West Ham United co-chairman David Gold says manager Sam Allardyce must sell to buy again.
Gold revealed that players must be moved on before any more can be brought in.
He told Sky Sports News: "We have reached our target laid down by the new rules in terms of wages.
"The only possibility now is if players are sold. That's up to Sam, that's in his hands. If he releases wages, that will give us the opportunity to bring in replacements for those players.
"I think it's clear that we are still short of a striker. David Sullivan agrees with that, Sam agrees with that, but until we release those wages by players leaving, there is little we can do.
"The next couple of weeks, we will see what happens."
