Pompey Ladies crashed out of the Premier League Cup with a 5-1 defeat to Lewes at The Dripping Pan.
The hosts started the third round tie on the front foot, although former Blues player Sarah Kempson had several unsuccessful attempts early on.
She eventually found the target, however, with a drive from the edge of the box that took a slight deflection off Eilidh Currie and nestled in the net.
Lewes soon doubled their advantage following a neat bit of passing play, with Katie McIntyre collecting a flick from Charlie Carter and slotting home.
Pompey tried to get back into the contest, only to find themselves further behind when Kempson fired a long-range effort into the top corner.
The visitors fought back after the interval and Daisy McLachlan’s cross was nodded narrowly over by Sammy Quayle.
And the deficit was reduced when Rachel Panting latched onto Katie James’ incisive pass, rounded a defender and slid the ball into the net.
Hopes of a comeback were dashed seconds later, however, as Lewes went straight up the other end and Vicky Carleton fired home an impressive strike.
Georgia Bridges then wrapped things up late on, with a shot from the edge of the box that flew into the bottom corner.
Blues boss Jay Sadler said: “We weren’t good enough at all and massive credit to Lewes because they pressed us well and were clinical.
"There were too many mistakes all over the pitch and although there were a few positives to take, overall it was embarrassing."
“We showed a lack of desire, hunger, passion and quality, but we came out well at the start of the second half and got hold of the ball.
“It was a great goal and then we had another 30 minutes to get a couple more. Instead we went gung-ho and then bang – we conceded and that was it.
“There were too many mistakes all over the pitch and although there were a few positives to take, overall it was embarrassing.
“We need to act more like a team and fight for it. We’ve also moved too far away from our ethos and are playing too direct.”
