Reiss Nelson was, unexpectedly, the star of the show as he scored twice after coming off the bench to replace injured Bukayo Saka.
Prior to that, Gabriel Martinelli had opened the scoring and Thomas Partey and Martin Odegaard also got on the scoresheet to complete the 5-0 win.
The win means Arsenal are now back at the top of the Premier League after Manchester City leapfrogged them on Saturday by beating Leicester.
Simon Collings was at the Emirates Stadium to see Arsenal in action…
Aaron Ramsdale 6
Had very little to do all afternoon as Arsenal dominated the game. Whatever happened to him, he handled it comfortably.
Ben White seven
Had another good game as he continues to impress in his new right-back role. He must surely be close to being in the England squad for the World Cup.
Guillaume Saliba 8
Another faultless central defender, who dominated the physical Taiwo Awoniyi. I didn’t take the wrong foot and looked so calm.
Had a heart-in-mouth moment where he passed the ball straight to Jesse Lingard in his own box. Other than that, it was solid and stable.
Takehiro Tomiyasu 8
Started the move for the first goal by winning the ball high up the pitch. Summed up his performance full of energy and racing.
Martin Odegaard 8
Created plenty of chances and allowed Arsenal to perform well in midfield. Got the goal his performance deserved with a great finish late in the game.
Thomas Partey 8
His passing was a little loose at times in the first half, but he stepped it up after the break. Entered the scoresheet with a superb long-range strike.
Xhaka Granite 6
A fairly quiet game by its high standards. Always tried to get forward as much as he could and was instrumental in Arsenal’s second goal.
Bukayo Saka 6
He started the game very well creating Arsenal’s opener with a superb cross for Martinelli. Obliged to leave before the half hour due to injury.
Gabriel Jesus seven
Should have scored as he missed several good chances. However, he worked hard for the team and finished the game with two assists.
Gabriel Martinelli 8
He looked much more like himself after a few quiet weeks. Took his goal very well by ducking to pass Dean Henderson.
Reiss Nelson (Saka 27′) 9 | star player
Who would have called that? Two goals and an assist from the winger, who has his chance here.
Fabio Viera (Martinelli 63′) 6
Came in for the last 30 minutes and had the odd good time, with some great touches around the box.
Cedric (Tomiyasu 63′) 6
A first appearance of the season for the Portuguese international, which was solid.
Kieran Tierney (Saliba 75′) N/A
Eddie Nketiah (Xhaka 75′) N/A
Unused Subs: Hein, Holding, Lokonga, Marquinhos
