Pompey saw their six-game winning run ended by high-flying Peterborough at Fratton Park last Saturday.
But a 2-2 draw at least managed to stretch their impressive unbeaten record to 10 games in all competitions.
And Tom Naylor hopes it can be extended further when the Blues pay a visit to Accrington this weekend.
After an inconsistent opening to the campaign, the midfielder insists that the squad are now full of belief.
Pompey’s skipper said: “We’re scoring a lot of goals and just need to tighten things up at the back a little bit.
“I think we’re pretty close to getting things right at both ends of the pitch and are climbing the league table.
"This time of the season is a great chance to pick up plenty of points and give yourself something to build on in the new year."
“We saw at the start of the season that it takes a bit of time to get things right, but we’ve gelled now and looking to keep pushing.
“I’m confident in the ability in this squad. We haven’t lost in 10 games and everyone’s feeling pretty confident.
“This time of the season is a great chance to pick up plenty of points and give yourself something to build on in the new year.
“Accrington are always hard to play against, but we’ve got a job to do – we’ve got to go there and make sure we do that.”
Naylor returned to the side against Posh after being kept out of action for a few weeks with a hamstring injury.
He said: “It was obviously a frustrating time for me to just be watching the boys when I wanted to be playing.
“So it was nice to get out there against Peterborough – I thought we should have got the three points – and the hamstring’s feeling fine now.”
