We were made to work hard by Cardiff City for our first away win of the Unai Emery era.
Shkodran Mustafi, Pierre-Emerick Aubameyang and Alex Lacazette all scored to give us an entertaining 3-2 win - but what did we learn from the game? Read on for some of the key points.
LACA BOSS
Alex Lacazette has had to wait patiently for his chance - and he did not waste it. Even before his venomously-struck winner at Cardiff he had been our standout player. Laca relished the battle, leading our pressing game from the front while taking a buffeting from two bulky centre backs.
