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:
9. IN: Mitchel Bakker
A deal for the Bayer Leverkusen left-back has been on, off, on and then back off. Is there another late twist? Photo: Christian Kaspar-Bartke
10. OUT: Elliot Anderson
Howe confirmed Anderson was left out of the trip to Saudi Arabia as Newcastle look to loan out the highly-rated teenager for some much-needed senior game time. Championship side Luton Town have long been admirers. Photo: George Wood
11. IN: Eddie Nketiah
Nketiah, whose contract at Arsenal expires at the end of the season, was linked with Newcastle over the weekend by the Daily Telegraph but has since been the subject of rejected bids from Crystal Palace. Photo: Ryan Pierse
12. OUT: Matty Longstaff
Recalled from his loan spell at Aberdeen, the chances of Longstaff breaking into Howe’s starting XI for the second half of the campaign is extremely unlikely. The 21-year-old needs gametime, whether that be in the Championship or League One. Photo: Ian MacNicol
