Pompey have won each of their past five matches at Fratton Park and conceded just one goal in the process.
It is a run of results that has seen them reach the brink of the top six and progress in the Checkatrade Trophy.
But that does not mean Kenny Jackett is completely happy with how his side have been performing recently.
And ahead of Saturday’s home clash with Northampton, he has challenged them to supplement solidity with more creative flair.
The Blues boss said: “Constructive and free-flowing football has to be the aim and we need to work out how to do that.
“There are times when our forwards shy away from 1v1 situations and taking people on with pace – it’s an area where we feel we can improve.
"It’s just about linking play better and attacking sides earlier to create more than we have done in the past few games."
“That can give us an edge and make us what we want to be – which is promotion contenders at the end of the season.
“But it can be tough to find a way to win and ultimately that’s the bottom line, so we have been pleased with results.
“It’s just about linking play better and attacking sides earlier to create more than we have done in the past few games.”
Pompey could find themselves in the play-off places with a couple of positive results in the next few days.
Jackett said: “It’s a big weekend for us with games against Northampton and Bristol Rovers in quick succession.
“We’ve played the first of those twice already this season and have one win each, so we won’t be underestimating them.
“Northampton are fighting for their lives down at the bottom of the table and will be working out their own way to get results.
“We want to be at our best and capitalise on the things we are doing well – and there are plenty of them.”
Pompey will still be without midfielders Stuart O’Keefe and Kal Naismith against the Cobblers.
Jackett said: “We’ll be selecting from the same squad and it’s good that we have no new injury worries.
“Stuart and Kal will be looking more towards the Chelsea game in the Checkatrade Trophy in January.”
