Valencia sports chief Miguel Angel Corona played down the prospect of buying in January.
Corona has hinted there are no funds to bring in new signings.
He said, "We have done an analysis of the squad since September 1, I think no one can say that the perfect squad exists.
"Any club, coach, sports director can tell you that they always find a gap where they can improve and we have an analysis done and what we will do is be prepared to, at the time when we are also financially able, to be able to complete a better squad."
Corona added: "I think we will know how to maintain the squad and compete until the end."
