All eyes have been on potential outgoings in recent weeks with the medium-term futures of Alexander Isak and Bruno Guimaraes up in the air as the likes of Arsenal and Manchester City are linked.
But for now the club need to focus on getting back into the Champions League, which may only require a fifth-placed finish this season.
Heading into the final days before the window opens, Newcastle are just two points off that spot with their trip to Old Trafford in hand.
And while their form is on the up with three league wins in a row, it was winter time last season when Eddie Howe's side's season fell apart - so they will be under no illusions about the need to keep the squad fresh and bolstered before the run-in.
