Andy Awford insisted he is not concerned after Pompey fired another blank.
The Blues picked up a goalless draw at struggling York City on Saturday in a match they had chances to win.
A worry for the Fratton faithful is they have now failed to net in six of their last nine matches in all competitions.
Similar to the previous weekend’s goalless draw at Hartlepool, opportunities fell their way – particularly late on in the fixture.
Jed Wallace, Danny Hollands and Craig Westcarr were the chief culprits, while debutant Ryan Brunt missed a sitter for the hosts in stoppage-time.
Regardless, the headache of goalscoring remains for Pompey.
But Awford is refusing to panic.
He said: ‘I cannot stress enough, I am not in the slightest bit worried about what I am seeing.
‘I was absolutely delighted with the overall performance on Saturday. I thought we were excellent.
‘We don’t need to do anything different apart from putting the ball into the back of the net and we will continue to work at it.
‘We will be back on the training ground today, there is a game tomorrow, we will be back out there Wednesday, Thursday, Friday and go again.
‘That is two now without scoring but we went Southend and Burton without scoring and then stuck three in against Dagenham.
‘Nobody is worried in the dressing room. I have every single confidence in the players and they have confidence in themselves that the goals will come.
‘They are all disappointed they didn’t take chances.
‘They are human beings, of course they are.
‘I am as well. But the way they are playing, I am pleased with the overall.
‘If they weren’t creating chances I would be worried.
‘But I am not in the slightest and have every confidence the goals will start to go in.
‘I have no worries whatsoever that sooner or later the floodgates will open and we will give someone a good tonking.’
The draw leaves Pompey in ninth position in the League Two table.
It came at the end of the week which saw the club announce its legacy debt had been cleared.
And for Awford, the progress on and off the pitch at present is obvious.
He added: ‘After two away trips we would have liked six points, of course we would, but we are unbeaten in four now since the second half performance at Southend.
‘We are getting some momentum going as a group and as a football club.
‘There was some great news for the club this week and it is improving on the pitch without a shadow of a doubt, I think everyone can see the improvement there.
‘Once we get going then the goals start coming then we will be fine.’
