Pompey Ladies endured an afternoon to forget as they suffered a 7-1 defeat to West Ham at Rush Green.
They started brightly, with Sammy Quayle and Daisy McLachlan both having chances in the opening minutes.
But the hosts broke the deadlock when Hannah Wheeler headed home from a corner, while Kelly Wealthall doubled the advantage after Ellie Zoepfl’s initial effort had been saved.
And the added a third goal before the break, courtesy of a fine curling effort from Rosie Kmita that flew into the bottom corner.
Jasmine Auguste extended the Hammers’ lead early in the second half, with another header from a corner finding the target.
Wealthall notched their fifth with a neat back-heel, only for the visitors to reply with a spell of pressure of their own.
McLachlan reduced the deficit with a free-kick from out wide, although the opposition players claimed the ball had not crossed the line.
They might have pulled another goal back when Rachel Panting was fouled in the box, but the winger’s spot-kick was well saved by Cara Connatser.
West Ham were more clinical, however, and Leanne Mabey nodded past Robyn Levett, before Wealthall wrapped things up by converting a Kmita corner to complete her hat-trick.
Blues boss Jay Sadler told the club’s official YouTube channel: “It’s a difficult one to take after all the progression we’ve made in the past few weeks.
“We’re trying to move in the right direction, but it feels like we’ve taken a massive step back and that’s disappointing.
"It’s about being more ruthless in both boxes and to concede four goals from set-pieces is pathetic."
“We just weren’t good enough all over the pitch and you have to question our mental strength and our ability.
“I back my players, but they didn’t perform and that’s a shame. We’ve got to look at ourselves and see what we can do to put it right.
“We had a spell in the game when we scored, but then missed a penalty and they went straight up the other end to add two more.
“So it’s about being more ruthless in both boxes and to concede four goals from set-pieces is pathetic. It was embarrassing and I can only apologise to the fans that travelled.”
