Perry Northeast felt Pompey Ladies had an off day in front of goal as visitors Coventry secured the win they needed to lift the title.
It was always going to be a dramatic final day of the season with so much riding on the contest.
Coventry needed a win to lift the FA Women’s Premier League southern division title.
Meanwhile, Pompey were still hoping for a top-three finish, if other results went their way.
But it was Coventry who were celebrating at the final whistle as they got the 1-0 success they needed.
Pompey joint boss Northeast believed it was just the finishing touch that was lacking from their good play.
He said: ‘We did everything but score.
‘It was just an off day in front of goal.
‘They took the lead early on and from then it was all one-way traffic as we pressed forward.
‘Not much was going on target but we created numerous chances.
‘Our corners were in double figures.’
Striker Charley Wilson was still ruled out after being injured in the FA Cup game against Notts County.
She could perhaps have made the difference on the day.
But Northeast was impressed with Coventry.
Twice they have beaten the Blues in recent weeks, without conceding a goal.
He added: ‘They did defend really well.
‘They have conceded only four goals in 10 games and have got two very good centre-backs.
‘Perhaps we needed to keep it away from them a bit more.
‘We could have looked to find another way through.
‘Any team would miss someone like Charley Wilson. She is a player for the big occasion.
‘She could have been the one to knock the goals in against Coventry.’
It would have been nice for Pompey to end the season on a high with a victory.
But Northeast was still pleased with the display.
He said: ‘We dominated the league champions for 90 minutes.
‘I felt we played very well. We have played worse this season and got a result.
‘It didn’t quite come together in the final third.’
