Arsenal secured their third consecutive home win at the Emirates Stadium on Monday night as Steve Bruce's Newcastle were overwhelmed by Mikel Arteta's side 3-0.
While the Gunners are yet to taste defeat in 2021, the Magpies have not been victorious in over a month but did not look like a side devoid of confidence.
In a tight first half, Arsenal had the better chances but could not find a way past the woodwork and some inspired goalkeeping from Karl Darlow.
After the break, Pierre-Emerick Aubameyang showed little patience and broke the deadlock with a fine finish into the top corner on the counter as Arsenal finally showed some cutting-edge.
Impressive link-up play between Emile Smith Rowe and Bukayo Sako saw the second arrive just 10 minutes later as the 20-year-old midfielder cut back to his younger counterpart, with Sako not losing his chance to score his fourth goal of the season.
To round off a brilliant night for Arteta, Cedric Soares set up Aubameyang to make it three in the Portuguese full-back's first Premier League start of the season.
Climbing back into the top half with three points, Arsenal also secured a fifth consecutive clean sheet, their best run since 2009.
