The Gunners are one point off the top of the Premier League after a 4-1 win over Blackburn Rovers on Sunday.
Arsenal, aiming to complete another double, have five games in hand over leaders Sunderland.
Blackburn's Rhiannan Roberts went from villain to hero in the first half, scoring a 13th minute own goal then equalising seconds before the interval.
The Gunners found their shooting boots after the break however, three goals coming in 20 minutes with Gemma Davison, Danielle Carter and Jayne Ludlow on target.
