Chelsea maintained their 27-match unbeaten run in the Women's Super League thanks to a late Lotte Wubben-Moy own goal in the 1-1 draw against Arsenal.
The Gunners missed the opportunity to go top of the table after taking the lead with just five minutes remaining.
Excellent work from Vivianne Miedema led to Beth Mead smashing the ball home in the 86th minute.
The visitors struck back just four minutes later as Pernille Harder's cross was deflected by Wubben-Moy and the ball looped into the back of the net.
The Blues had a glorious chance to settle the game late on as Sam Kerr raced through but her chipped effort rolled narrowly wide of the post.
