Alan Pardew has admitted his frustration at a failure to sign another two players and the Newcastle manager is conscious of the fact his squad requires reinforcements.
The St James' Park club continued their unbeaten start to the season with three points courtesy of two goals from Leon Best at Fulham on Sunday.
But Pardew remains keen to add to the summer signings of Demba Ba, Sylvain Marveaux, Yohan Cabaye, Mehdi Abeid and Gabriel Obertan before Wednesday night's deadline.
The departures of Jose Enrique and most recently Joey Barton have left Newcastle short and full-backs Erik Pieters and Aly Cissokho remain targets.
But Dutch media reports suggest a deal for the latter is off and the agent of Inter Milan defender Davide Santon claims talks are instead taking place with his client.
Pardew said in the Northern Echo: "I am frustrated that we have not got a couple of bodies in yet.
"Derek Llambias (managing director), Lee Charnley (club secretary) and Mike Ashley are as frustrated as me. Hopefully we will get over the line this week.
"There's nothing to update, we are at a point where in a few days we will know for sure what we have."
He added: "You can't disguise the fact that, in a week we lost Joey after losing Jose Enrique, we needed people to come out of the pack.
"Gabriel Obertan and Sammy Ameobi are doing that and I think Leon Best did that here. But we need reinforcements. I am not going to disguise that. We need reinforcements."
Italy international Santon is under contract with Serie A giants Inter until June 2014 and is also a reported target of Roma.
"At this time there is no possibility that Santon can join Roma because right now the aim is Newcastle," said Santon's agent, Claudio Vigorelli, to Corriere dello Sport.
