Brighton & Hove Albion ended a three-match losing run, holding Arsenal to a 1-1 draw at the Amex Stadium
Pierre-Emerick Aubameyang gave Arsenal a promising start, curling past Mat Ryan and into the far corner on seven minutes.
Aubameyang, the league's top scorer, might have scored his 14th PL goal on the half-hour mark, only to be denied by Ryan when through on goal.
Jurgen Locadia made him rue that opportunity, rounding off a swift counter-attack to draw Brighton level five minutes later.
The Seagulls had the better of the second-half chances, with Davy Propper heading just wide and Solly March lobbing over with Bernd Leno out of his goal.
Brighton lie 13th place with 22 points.
Unai Emery's side occupy fifth spot, with 38 points, two behind Chelsea.
Brighton: 29 Dec v Everton (H)
Arsenal: 29 Dec v Liverpool (A)
