Guy Whittingham played down suggestions of Pompey pulling off a great escape despite watching his side stretch their improved run.
The Blues defeated Coventry City 2-0 on Saturday to climb off the bottom of League One.
That’s now two defeats in their past nine matches – putting them five points off safety.
It represents a massive transformation for Pompey with six matches remaining of the campaign.
But Whittingham is not tempted to make grand survival statements.
The caretaker boss said: ‘We have got enough games to win a few and keep putting pressure on the other ones down and around us.
‘We know we have got 10 points coming off as soon as we come out of administration, so it is going to be difficult to stay up.
‘But what we can do is make sure it’s the 10 points coming off that makes the difference.
‘The crowd have kept us going for a long time.
‘Now things are starting to happen off the pitch – and now the players on the pitch and the performances have given the crowd something to cheer about.
‘Rather than the crowd getting us going, we are starting to get them going in games as well.
‘I think it’s the whole thing, momentum is building and we want to keep that up until the end of the season.
‘Everybody senses it around the club.
‘It’s nice everybody is being positive and the performances on the pitch are positive and that just puts smiles on people’s faces.
‘We have just got to keep doing the best we can and see where it takes us.’
