Pompey are the only League One side yet to taste defeat and currently sit second in the standings.
But that does not mean Kenny Jackett is completely satisfied with what he has seen from his side so far this season.
He feels that there are still plenty of upgrades required before they can be happy with performances.
And with eight games in the space of just 29 days coming up, there are plenty of opportunities to impress.
The Blues boss said: “We’re entering an intense period, with a lot of points to play for, and we’re looking for a good return.
“The league is obviously our priority, but we’ve got a cup game at Crawley in that time as well and we want as many wins as we can get.
"We’re looking to be a bit more cohesive and constructive in the middle third of the pitch. It’s about getting the balance right."
“There are a lot of things we’re doing right at the moment, but also some aspects where we need to improve – we’ve been focusing on those this week.
“We’re looking to be a bit more cohesive and constructive in the middle third of the pitch. It’s about getting the balance right.
“It’s been easy for sides at times to make it a bit of a stop-start game and we want it to be more free-flowing.”
Pompey secured a dramatic 3-3 draw when they visited Rochdale back in April and Jackett expects another tough test.
He said: “We go there in different circumstances than towards the end of last season, when they were fighting for their lives.
“They had a lot of games in hand to contend with back then and ended up doing extremely well to stay in League One.
“But it doesn’t make it any easier going there now and every single challenge is a big one for us in this division.
“My focus is on our own performance and I’m looking forward to some exciting games coming up – starting with Rochdale.”
Dion Donohue has missed the start of the season through illness and injury, but Jackett hopes he will be back in action soon.
He said: “Dion is training again and we’re perhaps looking to the Checkatrade Trophy game at Crawley if he can remain free of pain until then.
“Andre Green is obviously still out, but other than that we have a fully fit squad ahead of this batch of games.”
