Staring down the barrel of relegation, the Magpies knew they had to act in the market in order to stave off a third relegation in just over a decade.
After a busy start to the window, one that saw them add Kieran Trippier and Chris Wood to their ranks early on, the Magpies had a quiet couple of weeks before a flurry of action at the end of the month.
Matt Targett, Dan Burn and Bruno Guimaraes also joined during the dying hours of the window - but plenty of others were linked with a move to the club.
Here, we take a look at what has happened to 19 players that were linked with a move to Newcastle United last January.

. Hugo Ekitike
The Magpies had a deadline day bid for Ekitike accepted by Stade Reims, only for the striker to turn down the opportunity of moving to the north east. Ekitike joined PSG on-loan this summer but has struggled for regular game time alongside some of football’s biggest names. Photo: GEOFFROY VAN DER HASSELT
. Aaron Ramsey
Ramsey was touted as a potential option for Newcastle as he looked for a way out of Juventus. Instead, he moved to Rangers and was the unfortunate player to miss in their Europa League final penalty shootout defeat to Eintracht Frankfurt. He moved to Nice in the summer. Photo: LIONEL BONAVENTURE
. Dele Alli
Alli opted for a move to Everton last January, but failed to impress during his half a season at Goodison Park. The former Spurs man was shipped out to Besiktas on-loan, just six months on from his move to Everton. Photo: David Berding
. Ousmane Dembele
Dembele’s time at Barcelona looked like being over last winter, with Newcastle among many clubs eyeing a pre-contract deal, but the Frenchman has enjoyed a resurgence and is now regarded as one of Xavi’s key players. He helped France reach the World Cup Final in Qatar. Photo: David Ramos
. Todd Cantwell
Cantwell has recently joined Rangers after failing to impress at Carrow Road this season. In truth, Cantwell’s form had been declining for a while and a change of scenery was required to kickstart his career. Photo: Marc Atkins
. Philippe Coutinho
Coutinho was tempted back to England by Steven Gerrard as he linked up with his former teammate at Villa Park. After impressing during his time on-loan, Villa made his initial loan deal into a permanent one this summer. The Brazilian has failed to register a goal or an assist in all competitions this season.
