The Gunners were utterly dominant in the first half but it took a moment of real quality from Gabriel Jesus to break the deadlock. The Brazilian took the ball down to immediately turn Macros Senesi, before dribbling past three defenders and playing in Gabriel Martinelli. His shot was then saved but rebounded for Martin Odegaard to tap home.
Odegaard was then on hand to make it 2-0, firing home after Jesus mis-controlled Ben White's low cross. This was all within the first 10 minutes.
It wasn't long into the second half when William Saliba - who had had his name being sung by the Arsenal fans all game - made it three with a sublime finish from the edge of the box on his weaker foot. Here football.london takes a look back at some of the moments you may have missed from the game.
