Fratton Park was at its vociferous best during Tuesday night’s League One victory over Exeter.
And John Mousinho is hoping that is a sign of things to come when his side are on home soil this season.
Pompey head into Saturday’s south coast clash with Cheltenham looking to build on their unbeaten start to the season.
With seven points out of nine collected and Carabao Cup progress assured, Mousinho feels that his squad are starting to show what they are capable of.
The Blues boss said: “We’re getting there and a big part of getting that identity right is being able to mix things up when required.
“When it’s on to play, we do that and then also have the ability to be a bit more practical, particularly when sides are pressing us.
“There are also some really important bits off the ball that we’re looking to nail down and it’s important to see that things are coming together, while still having room for improvement.
"We’re getting there and a big part of getting that identity right is being able to mix things up when required."
“I thought the atmosphere were absolutely incredible the other night – positive from the off – and that really helps.
“I’ve spoken about that cauldron ever since I arrived at the club and we want to make it a difficult place for clubs to come.”
Pompey will be expected by most to beat a Robins side who have not collected a point or scored a goal so far this term.
Mousinho said: “We’ve got to harness that and know that if we can’t get the job done in the first 45 or 60 minutes, then we have to be prepared to dig in for the long haul.
“As long as we’re showing attacking intent, then the fans will be fine – and it’s something we’ll always try to do.
“We will take the momentum from the start to the season and look to keep going on the same pathway.
“But we know that Cheltenham are coming here with a point to prove after a tricky opening, which provides them with an added incentive.”
