Tom Craddock admitted his maiden Pompey goal was scant consolation in defeat.
The Blues’ losing run continued as the 2-1 reverse to Scunthorpe made it four on the bounce.
Craddock opened his goal account, however, with the opener – before two strikes from David Syers turned the game on its head.
The 27-year-old was pleased to get up and running but left the match unhappy in defeat.
Craddock said: ‘It’s gutting.
‘I’m pleased to get the goal but the over-riding feeling is I’m gutted.
‘We have to reflect on this but we can’t dwell on it for long because there’s another game coming up.
‘I feel good. I’ve been working hard and doing my extras.
‘It normally takes six weeks to get to full fitness, so there’s still a way to go.’
Pompey’s defensive deficiencies again proved crucial to their downfall on Saturday.
Syers was left unmarked for the opener from a corner before he reacted quickest after Trevor Carson saved Sam Winnall’s shot.
Craddock knows that must quickly be put right if his team are to turn their season around.
He said: ‘We don’t like to get beat.
‘We’ve just got to try to put it right.
‘As a team we have to be more solid.
‘You can see we need to work on that.
‘It’s not just the defence but the team as a whole.
‘It’s me up front and the wide men as well.
‘We’re not giving ourselves any sort of foundation at the moment.
‘We have to start doing that and try to keep goals out of our net.’
Pompey now have a quick chance to turn their fortunes around as they face Southend tomorrow.
The Essex outfit arrive at Fratton Park in decent form after four wins on the bounce.
In contrast, Guy Whiitingham’s side go into the game low on confidence as their losing form continues.
Craddock feels it is now going to take bravery for Pompey to get their campaign firing again.
He said: ‘There is only one way to get through this.
‘That’s to be brave, stick our chests out and get on with it.
‘The fans aren’t happy but neither are we as a team.
‘The only way to turn it around is by getting out there and working hard.’
