Tottenham 0-3 Arsenal
Republic of Ireland captain Katie McCabe scored one and made another as Arsenal ensured Tottenham's winless streak stretched to seven Women's Super League matches.
Caitlin Foord, Vivianne Miedema and McCabe were on target for the Gunners in a 3-0 north London derby victory.
The visitors could have been ahead early on after Jordan Nobbs' two long-range efforts forced Rebecca Spencer into making good saves.
The Gunners made the breakthrough after 25 minutes when Foord combined with Noelle Maritz on the right-hand side before slotting the ball into the bottom corner.
Arsenal doubled their advantage in the 34th minute after a Miedema wonder-strike, with the Holland international volleying home a McCabe corner.
Arsenal completed the scoring in the 60th minute after McCabe pounced on a defensive error before calmly rolling the ball into the back of the net.
Later, Chloe Kelly's last-gasp winner earned Manchester City a 1-0 win over Reading to turn up the heat on Chelsea in the title race.
Kelly, who had a penalty saved in City's 3-0 Women's Champions League defeat to Barcelona in midweek, struck in the 87th minute to take City a point clear of Chelsea at the top of the table. The Blues can regain top spot on Sunday.
City threatened first when Demi Stokes whipped a low cross that found Lucy Bronze, who squared the ball to Rose Lavelle and her effort was tipped over by Grace Moloney.
The Reading goalkeeper then produced saves from Bronze and Caroline Weir to keep her side on terms.
At the other end Reading forward Amalie Eikeland had a close-range effort that forced Ellie Roebuck to save with her legs.
But, unsurprisingly, almost all of the pressure was coming from City and Georgia Stanway's low effort flew inches wide of a post.
Moments later a glorious opportunity fell to Lauren Hemp, but her close-range effort hit the woodwork and Reading cleared.
Gareth Taylor's side kept pressing as substitute Sam Mewis' diving header went just wide and Weir saw a fine cross palmed away by Moloney.
City finally broke the deadlock three minutes from time as Hemp burst down the left and found Kelly, who tapped home from close range to secure an important win.
