Arsenal underlined their Premier League title credentials as they recorded their sixth consecutive win with a dominant display against Newcastle.
The result sees Mikel Arteta’s side sit two points behind leaders Liverpool and a point behind second-placed Manchester City at the top of the table.
The outcome of this contest appeared inevitable from the moment visiting defender Sven Botman turned the ball in after Gabriel’s header from a corner had been well saved by Newcastle goalkeeper Loris Karius.
While there was an element of bad luck to that for the Dutch defender, who simply could not get out of the way as his Newcastle team-mate Tino Livramento tried to clear, there was little else about Arsenal’s performance that was owed to good fortune.
The Gunners’ intensity and fluent passing repeatedly carved Eddie Howe’s side apart, particularly down the Magpies’ left flank with Livramento and Botman enduring difficult evenings.
Kai Havertz swept in a deserved second shortly after, with Gabriel Martinelli making the most of indecision in the Newcastle defence to cut the ball back into the German forward’s path.
With Arsenal continuing to press, Bukayo Saka twisted and turned Livramento one way and then another before dispatching a left-foot shot into the bottom left corner add to the hosts’ advantage.
Arteta also enjoyed the luxury of being able to take off his captain Martin Odegaard, Havertz and Saka well before full-time after Jakub Kiwior’s effort deflected past the helpless Karius from another Declan Rice corner.
Newcastle, who remain eighth in the table, managed a late consolation courtesy of Joe Willock’s looping header, but there was little else for the visiting supporters to cheer.
