Pompey Ladies boss Vanessa Raynbird was left disappointed as her side’s flying campaign stalled against Coventry.
She watched her team suffer a 1-0 loss to the Sky Blues at Dover Road.
That put the brakes on their FA Women’s Premier League national division progress.
Pompey were second in the table going into the game after their success at Manchester City last time out.
But Coventry got the only goal of the match, midway through the second-half in the game’s decisive moment.
It was Helen Dermody who did the damage in impressive style, as she scored directly from a corner.
Coventry’s powerful rearguard action nullified Pompey’s attacking threat.
Raynbird said: ‘It was disappointing.
‘They had a couple of really good centre-backs who stood strong and stopped our quick forwards, Gemma Hillier and Charley Wilson, from getting in behind.
‘Their keeper was also fantastic. She picked everything out of the air.
‘We are a better side than them on our day but we gave the ball away. We had three or four good chances but couldn’t take them.
‘Sadie Blakely made a couple of good saves.
‘We deserved a draw out of the game though.
‘It was really disappointing because we have got better results against sides who have played better than Coventry.’
