West Ham United Ladies fell to a 3-0 defeat at Lewes on Sunday as the hosts' power from set plays paved the way to victory.
Two goals from corners for the FA Women's Premier League Southern Division high-flyers proved too much for the Hammers to come back from, with the absence of several key players through injury taking its toll.
The Sussex side took the lead two minutes before the break through a Leeta Rutherford goal, sealing the points after half-time as Katie McIntyre and Rebecca Carter got on the scoresheet.
A disappointed first team manager Greg De Carnys said: "We have to be braver and play our game - play the way we can.
"Ultimately, our decision making wasn’t good enough and we weren’t good enough on the ball. We have missed key players that would help us look after the ball better during a period of important games, and hopefully that will change soon.
"Amber Stobbs looks like she will be back this week having not played in the league since our last win against Cardiff and she will be a big addition.
"Right now the girls' confidence has taken a knock, but if we can get ourselves a win we can start to rebuild that and hopefully get some momentum going.
"We have to show a massive improvement against Swindon and the staff and I are working as hard as we can to turn it around."
West Ham Ladies are back in action this Sunday when they host Swindon Town at Rush Green. Kick-off is at 2pm, with admission free for Season Ticket Holders and all under-16s. Adult tickets are priced at just £2.
