Charlton Women grabbed all three points away to Brighton in the Subway Women’s League Cup.
Mary McAteer’s cross in the 18th minute went straight into the net, while Addicks goalkeeper Anna Pedersen kept a clean sheet.
Emma Bissell struck the bar for the WSL2 side, while Caitlin Hayes was denied an equaliser by the post.
While Albion finish their group fixtures on six points, Charlton trail them on goal difference with a game to go.
Also in Group C, West Ham United ran out 5-0 winners over Southampton to move three points clear at the top.
The second-tier Saints had held the Hammers at bay until the 64th minute, when Viviane Asseyi made the breakthrough.
Shekiera Martinez and Ffion Morgan scored to put the result beyond doubt, with the former completing a brace in added time along with Asseyi.
