Martin Zubimendi's double and Viktor Gyokeres's tap-in gave Arsenal a comfortable 3-0 home victory over Nottingham Forest in the Premier League on Saturday, condemning Ange Postecoglou to defeat in his first game as Forest boss.
Spain midfielder Zubimendi's first Arsenal goal, a stunning volley in the 32nd minute, capped a dominant first half for the hosts, though captain Martin Odegaard was forced off injured after falling heavily on his right shoulder.
Arsenal doubled their lead within a minute of the restart, Eberechi Eze capitalising on poor defending by substitute Nicolo Savona to lay it on a plate for Gyokeres to score his third of the season.
The game was petering out when Zubimendi put it to bed in the 79th minute with a simple header from Leandro Trossard's cross, prompting gleeful chants from Arsenal's fans towards Postecoglou, former manager of their bitter rivals Tottenham Hotspur.
