After the scoreless contest ended at the end of the 90 minutes, overtime forwards from fit youngster Emile Smith Rowe and captain Pierre-Emerick Aubameyang sealed the Gunners’ route for the next round.
The victory over the Magpies was a fourth successive triumph in all competitions for Mikel Arteta’s side, which means their recent troubles are only a distant memory.
Specifically identifying the catalyst for Arsenal’s recent resumption of fortunes is a guess, but the regular introduction of the club’s young players, such as Bukayo Saka and Smith Rowe, has played a key role.
While these two played a key role in changing the Gunners’ fortunes in an offensive sense, their defensive qualities have also improved, with Arteta’s side keeping three clean sheets in as many games.
And one man who played a central role in that achievement is left-back Kieran Tierney, who produced another impressive performance against the Magpies, a week after playing in the 4-0 win over West Bromwich Albion at the Hawthorns, who saw him score a superb solo effort and claim an assist.
Following the win over Newcastle, which earned him another assist, the Scotland international received praise from former Magpies striker Alan Shearer, who was covering the game as an expert for the match of the day.
“What about Kieran Tierney’s work? The best player in the park, ”Shearer told BBC Sport.
“The giving, the go, it’s great to sit down and watch it and the balls he put in and the quality he has with that left foot in there.
“And for him to choose it [Aubameyang] like he did and get that position like i said he was the best player in the park. ”
Tierney’s impressive performances in recent times have left Arsenal fans with plenty to shout about, with many predicting that he could soon challenge compatriot and Liverpool full-back Andy Robertson for ‘the Premier League’s best left-back’.
But aside from making Arsenal fans delighted with Tierney’s current form, he also proved that Jose Mourinho – Tottenham Hotspur head coach – was right in his prediction on the Scotsman.

After arriving in north London in 2019, Mourinho leaned the attacked full-back as a smash hit, which despite his injury issues he certainly has the capacity to be for years to come.
Mourinho told Sky Sports: “Tierney is like a young Nacho Monreal. He has the same kind of profile. He is reliable, has a good character, has a great personality.
“He looks a bit like someone from a previous generation in some ways.
“He has a humble way of behaving and I like his profile.”
This season, Tierney has racked up 22 appearances in all competitions for the Gunners, scoring one goal and claiming three assists.
