Olivia Smith’s strike on 17 minutes was the difference between the teams at the Emirates Stadium as Andrée Jeglertz’s side lost for the first time since the opening day of the term.
The Blues entered the meeting chasing a league record-equalling 14th straight top-flight win, and after a breathless opening exchange, it was the hosts who opened the scoring.
MATCH REPORT | ARSENAL 1-0 CITY
Mariona Caldentey played Smith into the box before she rounded Ayaka Yamashita and tapped into an empty net.
Our goalkeeper was then called into action ahead of half-time when she made great saves to deny Katie McCabe, Alessia Russo and Beth Mead.
Following the interval we grew into the game and continued to press for an equaliser, but the precious goal evaded us as we failed to score for the first time in the league this season.
