The Magpies have until 11pm tonight to further bolster a playing squad that has seen Kieran Trippier, Chris Wood and Bruno Guimaraes arrive so far.
At least one key position remains left to fill, with a central defender top priority to help improve a backline that has conceded 43 Premier League goals this season.
But don’t rule signings in other areas of the pitch too as United’s recruitment team seek to provide Eddie Howe & Co with the best chance of achieving top-flight status.
Beyond that, players are also expected to leave St James’ Park as well, whether that be on loan or a permanent basis.
Howe must select a 25-man squad and naturally, with three arrivals so far, that means three current first-teamers will need to be removed.
It’s set to be a busy day – and here, NewcastleWorld takes a look at the deals – both ins and outs – that COULD happen across the day:
13. IN: Matt Targett
Reports on Sunday night suggested the Magpies had upped their interested in the Aston Villa full-back. Targett has fallen down the pecking order at Villa Park following Lucas Digne's arrival from Everton. Photo: Ryan Pierse
14. OUT: Dwight Gayle
Could depend on Newcastle signing a striker. Gayle, out of favour and out of form for a while now, is the club’s only fit striker behind Chris Wood. Callum Wilson isn’t back until March at the earliest. Photo: Michael Regan
