Maria Thorisdottir's 85th minute strike earned Chelsea a thrilling victory over Arsenal, which means Manchester City are now outright leaders at the top of the Women's Super League.

In the big match of the WSL weekend, Danielle van de Donk gave Arsenal a ninth minute lead after a clever pass from striker Vivianne Miedema but Chelsea recovered and levelled soon after half-time. Beth England turned the ball in from a Fran Kirby cross and just five minutes from time, substitute Thorisdottir curled in a stunning goal to condemn Arsenal to their first defeat of the season.

As a result of the victory, Chelsea are now one point ahead of Arsenal and trail City by just two points.

Tessa Wullaert turned in a cross three minutes into the second half and 10 minutes from time, Lee Geum-min's finish ensured victory.

City have now kept four clean sheets in the league from four matches and have won their first seven games of the season in all competitions.
