Perry Northeast felt training ground planning was key to Pompey Ladies’ fine 2-1 victory at Keynsham.
The win saw the Blues climb back up to second spot in the FA Women’s Premier League southern division.
Defender Fiona McMillan and striker Charley Wilson got the goals on Sunday.
Both strikes came from Molly Clark corners.
It’s something joint Blues bosses Northeast and Katie Poore have been working on with the team.
Northeast said: ‘It’s good to see something come off like that in the match.
‘The first goal was a great delivery from Molly.
‘Someone just had to meet it and Fi was on the end of it to direct it into the net.
‘Fi was dominating in the air – in defence and attack.
‘The second goal was a Molly Clark corner again and we’ve been working on that.
‘Charley got the touch – that was pleasing.
‘It justifies why we work on stuff in training.
‘We’ve won a game from two corners we worked on recently and that shows the importance of having to do that.’
Wilson and Gemma Hillier both came close to scoring before Pompey took the lead.
Clark’s superb corner delivery led to McMillan heading the ball into the net on 22 minutes.
Pompey came under pressure just before the break.
But a combination of a good save from keeper Sadie Blakely and some last-ditch defending from Tiff Taylor, on the line, ensured they went into half-time 1-0 up.
Pompey started the second period well and doubled their lead.
Clark again took the corner and it fell to Wilson who was able to force the ball over the line.
Pompey were unfortunate to go down to 10 players for the final stages of the contest.
McMillan had to go off injured and the Blues had already used their three substitutes.
Keynsham then got a goal back with five minutes to go.
Clark was penalised for a tackle in the box – a decision Pompey strongly disagreed with.
But Keynsham netted the penalty.
That made for a nervous finish but Pompey Ladies held strong to close out their victory.
Tonight the Blues are in friendly action at Furze Lane when they take on the Columbus University Ladies team (7.30pm).
It promises to be a good occasion for the club and fans are welcome to attend.
The match will serve as important preparations for Pompey’s FA Women’s Cup last-16 clash.
They take on Super League side Durham at Privett Park on Sunday (1.07pm) and will be hoping for a big crowd.
