Arsenal reclaimed top spot from their North London rivals Tottenham following their 2-1 victory over Swansea in today's late kick-off.
After a goalless first half, Serge Gnabry opened the scoring for the Gunners in the 58th minute. Aaron Ramsey then doubled their lead four minutes later with a fine finish.
Ben Davies' 82nd-minute volley gave the Swans hope, but Arsene Wenger's side held out to claim the victory and extend their record to 12 consecutive away matches.
The result means Arsenal have not dropped a league point since the opening game of the season.
Swansea have dropped to 13th in the league, but will hope to improve on that position with wins in their forthcoming matches against Southampton and Sunderland.
