A wonderful 17th-minute goal by Olivia Smith helped **Arsenal** consign Women's Super League leaders **Manchester City** to a first defeat since September.
City had not lost since the opening day of the season but Andree Jeglertz watched the 17-match unbeaten run of his pace-setters end at Emirates Stadium.
Smith raced onto a wonderful Mariona Caldentey pass and rounded Ayaka Yamashita to score her seventh goal for Arsenal.
Even though WSL leading scorer Khadija Shaw threatened before and after half-time, Renee Slegers’ side held on for a vital three points.
Ireland skipper Katie McCabe played over 80 minutes for the Gunners in north London.
**Chelsea** returned to winning ways in the WSL with a 2-0 victory over **Tottenham**.
In their last two outings, the Blues were thumped by Manchester City along with a defeat to Arsenal and they went ahead at the Tottenham Hotspur Stadium through Keira Walsh.
Alyssa Thompson doubled their advantage early in the second half as Chelsea stayed third in the standings and went four points clear of Spurs, who remain fifth.
Courtney Brosnan was the player of the match in Everton's win over London City
**Liverpool** moved off the bottom for the first time since November with a fine 4-1 win over an **Aston Villa** side captained by Anna Patten.
It took the Reds 12 matches to get off the mark in the WSL this season, but they made it two wins in three after goals by Mia Enderby, Martha Thomas, Grace Fisk and Aurelie Csillag in St Helens.
Enderby and Thomas scored within 14 minutes and while Miri Taylor reduced the deficit before the break, Fisk and Csillag struck late on to help Liverpool leapfrog relegation-rivals Leicester.
Denise O'Sullivan continued her form for the Reds, playing the full game, and picking up a yellow card.
**West Ham** were set to go bottom after they went two goals down at home to **Brighton** before they produced a remarkable turnaround to win 3-2.
Manuela Vanegas put Brighton 2-0 up after 63 minutes following Kiko Seike’s 40th-minute opener, but Ffion Morgan gave the hosts a lifeline with eight minutes left when her cross caught out goalkeeper Chiamaka Nnadozie.
Shekiera Martinez levelled in the 86th minute before Viviane Asseyi completed the comeback after a goalmouth scramble in the first minute of stoppage-time to spark wild celebrations.
**Everton** responded to the midweek dismissal of Brian Sorensen with a 1-0 triumph at **London City**.
After a goalless first 45, Inma Gabarro broke the deadlock in the 62nd minute.
It proved enough to help Everton register back-to-back WSL wins for the first time this season after a string of saves by goalkeeper captain, and Ireland international, Courtney Brosnan.
