Alessia Russo scored the only goal to hand Arsenal a 1-0 win over Tottenham in the north London derby in front of another sold out crowd.
The Gunners sold out the Emirates Stadium for a second straight game as 60,050 watched the hosts keep the pressure on in the Women’s Super League title battle.
Russo provided the winning moment four minutes after the break, lashing home from six yards after being set up by England team-mate Beth Mead.

Emma Koivisto scored twice as Liverpool beat Aston Villa 4-1.
Grace Fisk’s deflected strike in the 19th minute gave Liverpool a lead and Sophie Roman Haug added a second before Sarah Mayling pulled one back from the penalty spot.

Brighton beat rock-bottom Bristol City 7-3 to move eight points clear of the relegation spot.

Two goals in three minutes from Brooke Aspin and Amalie Thestrup brought Bristol City right back into the contest.
