Crystal Palace manager Sam Allardyce has refused to give up hope on adding Carl Jenkinson and Patrick van Aanholt to his relegation-threatened squad this month.
The Palace boss is desperate to bring in fresh faces to a side which faces a battle to retain its Premier League status following a troubled first half of the campaign.
The south London club, who host an Everton side fresh from their impressive 4-0 victory against Manchester City, have not won in their last seven league matches while Allardyce, who has never been relegated as a top-flight manager, is also chasing his first league victory since taking over from Alan Pardew.
Jenkinson and Van Aanholt have both been earmarked by Allardyce, but earlier this week it was suggested that a move for the Arsenal defender had collapsed. Meanwhile, Sunderland manager David Moyes revealed on Friday that Palace are yet to return with an improved offer for their full-back Van Aanholt.
"Until the chairman rings me up and says the Carl Jenkinson deal is dead, it is still ongoing for me and the same with Patrick van Aanholt," Allardyce said.
"Until we hear that Sunderland are not selling, we are interested. Whether they have got any farther, the chairman will update me later on today or tomorrow."
Allardyce has added only one new face - Jeffrey Schlupp from champions Leicester - to his side, who are just one place above the drop zone.
The former Sunderland manager claimed he missed out on midfielder Jake Livermore, who completed his move from Hull to West Brom on Thursday.
During his short spell at the Stadium of Light, Allardyce moved to sign four players in the last January window which he believes kept the club in the top flight.
"I wish I could be very confident and say I could find four players like I did at Sunderland who will all make such a big contribution to the team, and that they would save the club from relegation," Allardyce added.
"I will try my hardest in this window to buy or loan players to improve the squad.
"We are not sure where we will end up. We have got one, but have missed about 20 where offers have gone in. We are in for a lot of players and at the moment and we are not having too much success."
Palace host Everton bolstered by their midweek FA Cup third-round replay victory against Bolton.
And Allardyce, whose squad were forced to train at Selhurst Park on Friday after their pitch at their training headquarters in New Beckenham froze over, has called on his side to get points on the board from Saturday's tricky fixture against the Toffees.
"We have got to stop losing, that is for sure," said Allardyce.
"There wouldn't be too much pressure from me to say to the players 'you have got to go and win it' because they are already under enough pressure.
"It is about being capable of producing a performance to get a result. If that is a win, it will be fantastic. If it is a point I will be relatively satisfied that we have stopped this bad run of losses."
