During that month, the Toon brought in the likes of Kieran Trippier, Dan Burn and Matt Targett to try and stem the tide of leaking so many goals and avoid getting relegated.
This ended up working wonders for the Magpies, as they only lost five league games after January, four of which were against the teams who ended the season in the top four.
Now that the summer transfer window is set to open, this will once again give Howe the chance to strengthen his squad and put them in a good place to take on the next campaign.
One figure with whom Newcastle have been linked recently and who could potentially make them even stronger at the back is William Saliba.
In the summer of 2019, Arsenal signed the defender in a deal worth a reported £27m. Since then, the £27m-rated Frenchman has had loan spells in his homeland with clubs such as Saint-Etienne, Nice and Marseille.
His recent campaign on loan with Marseille saw the 21-year-old show his capabilities at the back by making more interceptions (80) and clearances (91) than any other player at the Stade Velodrome. He also made more tackles (47) in the defensive third of the pitch than any of his latest crop of temporary team-mates.
As one of Europe’s most highly-decorated players, the opportunity to have Newcastle’s own next version of Varane in the shape of Saliba would be a mouth-watering prospect for Howe.
Presumably as a result of playing 14 more league games than the Manchester United defender this season, the Gunners outcast racked up more tackles, interceptions, blocks and pressures than the 2018 World Cup winner.
If Newcastle sense an opportunity to sign the young centre-back either on a permanent move or loan deal from Arsenal this summer, it is something that they should definitely pounce upon, as the 21-year-old certainly seems to have what it takes to show that he can succeed in the Premier League.
