Arsenal secured a 2-0 victory over Brentford, extending their lead at the top of the Premier League to five points.
Mikel Merino opened the scoring with a header, and Bukayo Saka sealed the win in stoppage time.
Arsenal's centre-back Cristhian Mosquera was forced off injured, adding to their existing defensive concerns.
Brentford's Kevin Schade came close to equalising, with his header spectacularly tipped onto the crossbar by Arsenal goalkeeper David Raya.
The Gunners extended their unbeaten run to 18 matches in all competitions and recorded an eighth consecutive home win with a clean sheet.
