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:
5. IN: Jesse Lingard
Could there be any late movement on this one? It’s unlikely but never say never. Lingard wants the loan move - and he’s far from happy with Manchester United after they quoted some absolutely extortionate figure to Newcastle. Photo: Matthew Peters
6. OUT: Jeff Hendrick
New manager, same outcome for Hendrick. The Republic of Ireland international has played just 10 minutes since Howe arrived. Will likely drop further down the pecking order now Bruno Guimaraes has joined. Photo: Naomi Baker
7. IN: Diego Carlos
Another one to put in the unlikely category but again, don’t rule it out. Newcastle desperately want to sign the Brazilian having chased him all month, but Sevilla will need to lower their ever-changing demands. Photo: Fran Santiago
8. OUT: Ciaran Clark
The knives are out for Clark at the moment after the defender was sent off in a friendly with Saudi Pro League leaders Al-Ittihad. Harsh criticism? Perhaps, though some supporters haven’t forgiven his for Norwich sending off. Photo: Stu Forster
