There were loud appeals for a penalty when an Aubameyang header appeared to hit an Everton hand after 54 minutes, but two minutes later the Gunners had the lead as Ramsey played in Lacazette, who lashed home.
Cech preserved his first clean sheet of the season as he pushed away Cenk Tosun's shot from just outside the area on 85 minutes to cap off an impressive performance in goal.
