David Norris makes his Ipswich return tonight and insisted: The belief is back.
Norris feels Pompey go to Portman Road with confidence flowing again after the weekend success over Barnsley.
The 30-year-old will return to the club he left in the summer for the first time since moving to Fratton Park.
Norris will be pumped up for the occasion after spending three years with the Tractor Boys.
His 20-yarder against the Tykes on Saturday proved the key moment and put paid to a run of four defeats in five for the Blues.
Now he feels there is the faith Pompey can build on that win against a team also showing fine form.
Norris said: ‘We’re going back to Ipswich and I can look forward to that.
‘Hopefully, we can go there with a bit of confidence because they’re flying, too. We are going to need to go there with confidence.
‘It will be difficult, but after the Barnsley result, we’ll make a game of it.’
Norris believes inconsistency has been Pompey’s downfall throughout a stuttering start to their Championship campaign.
But the hope is the victory in the first game of the post-Steve Cotterill era can breed a solid run of form.
Norris said: ‘Obviously, you’re not going to play well every game.
‘But at times, when you are not playing well, you need everyone else to carry you along – but I think there were many of us not playing well.
‘We seemed to play well one week and then not so well the next.
‘We were a bit inconsistent but, hopefully, we have sorted that out now.’
