De Jong arrived at St. James' Park from the Bundesliga side in a loan deal until the end of season, but the Magpies faithful are having to deal with the aftermath of Yohan Cabaye's exit to Paris Saint-Germain, whilst his proposed replacement Clement Grenier turned down a move to the North East from Lyon.
But whilst there are a number of problems for Alan Pardew's side, the Newcastle boss could be poised for a boost with the news that Benfica winger Filip Djuricic could be set for a move to the club.
Djuricic's agent Ulisses Santos confirmed to the Portuguese press that he had spoken to Pardew regarding a move, and the Magpies will be looking to push through a deal for the Serbian wide man on deadline day.
"Yes, the news about Newcastle is true. I have spoken to Alan Pardew this week. Let's see what happens by the end of Friday." said Santos.
The 21-year-old only moved to Portugal in the summer, having impressed during a three-and-a-half year spell in Holland with Heerenveen. However, the Serbian international has struggled to break into the team after his €6m switch, with the likes of Nicolas Gaitan, Miralem Sulejmani, Eduardo Salvio and Lazar Markovic seen as higher in the pecking order by manager Jorge Jesus.
As a result, Djuricic is looking the leave the Estadio da Luz this month, with Celtic also looking at a move for the winger, but a move to Newcastle looks far more appealing at this stage in Djuricic's career.
If Pardew is planning to play de Jong and Loic Remy up front together, Newcastle may switch to a 4-4-2 system, especially with Cabaye now with PSG. The addition of another winger would be vital to this switch, which makes Djuricic a sensible target with the deadline drawing ever closer.
