Martin Zubimendi scored his first Arsenal goals as the Gunners beat Nottingham Forest 3-0.
Former Tottenham manager Ange Postecoglou had not beaten Arsenal boss Mikel Arteta in the previous four matches they had gone head to head, and this time was no exception.
Arteta will be delighted with his side's performance, but will be concerned by captain Martin Odegaard picking up a shoulder injury in the first half.
