The administrators of Derby County say they hope to be able to name their preferred bidder soon as conversations with prospective buyers continue.
It comes after the ELF said it understood the club had enough cash to trade until the end of the season.
Derby has faced months of turmoil after going into administration in September, being set deadlines by the EFL to prove it had money to keep trading and facing compensation claims from Middlesbrough and Wycombe Wanderers.
A number of potential bidders have shown interest in taking on the Championship side, although some have already dropped out of the running.
A spokesperson for the administrators at Quantuma said: "The joint administrators are in active dialogue with prospective purchasers of the club and are working with their advisers to clarify a number of matters relating to their bids.
"Due to the complex nature of the mechanics of the bids received, it is necessary for us to work through each of these matters individually, to ensure the bids meet our terms of purchase.
"Whilst we understand the frustration of fans, who are understandably anxious that the club’s future is resolved, we remain confident that we will be in a position to name a preferred bidder shortly.
"We welcome the support received from the EFL yesterday and will continue working with them, and everyone who has the Club’s best interests at heart, to secure the best long-term outcome for Derby County."
On Wednesday the EFL warned a "lack of progress" was "threatening the very future" of the club.
The following day it said: "The EFL Board considered the latest information provided by Quantuma (Derby County administrators), including their forecast which showed the club has sufficient cash to trade until the end of the season.
"It is clear that there are still a number of challenges to be dealt with by the Administrators as they work to confirm the preferred bidder status and exit the club out of administration."
