Ben Chorley is gunning to lead Pompey to a top-10 finish to cap his whirlwind fortnight.
The Blues will face Plymouth with a Fratton Park full house on Saturday for the final match of the season.
Victory would mean ending the campaign in 10th spot – while they could even take ninth place if Bury fail to defeat Morecambe.
Chorley returned to Andy Awford’s side in the remarkable 4-4 draw at Bury following six matches on the sidelines.
That included time out for a four-match ban, the birth of his son Frankie and the form of Jack Whatmough and Bondz N’Gala.
Now Pompey’s skipper is pushing to keep his spot against Argyle and maintain the Blues’ outstanding recent momentum.
He said: ‘It’s always a pleasure playing for Portsmouth.
‘I’m not just saying that, I came here to see the team stay up and that is what has happened.
‘The manager might not thank me for saying it but I think next season we are in for a massive chance.
‘Everyone is so confident at the moment and it would be great to finish the campaign in the top 10, especially from where we were a month ago.
‘Defensively we will get better (from Bury) and I was pleased to get through my first 90 minutes in five weeks.
‘I am always confident in my own ability but the boys had won five in a row, so it doesn’t matter if you are Tony Adams, you don’t expect to play.
‘While I’ve been out I’ve had very good chats with the gaffer. He’s a professional, and spoke to me about an awful lot of things.
‘You look at the centre of defence and Jack is 17.
‘I didn’t make my debut until I was 21 so it just shows you how far the manager is willing to put his faith in young Jack.
‘Bondz has done well, you know what you are going to get with him, while Sonny (Bradley) and Joe (Devera) won 1-0 away from home at Northampton so nobody can say they didn’t play well, so I was very fortunate to get the shirt at Bury.
‘Now we’re looking for one last push to break into that top 10.’
Chorley has made an impressive impact since his January arrival under Richie Barker and proven to be an excellent signing.
And the Dartford-based 31-year-old has to cope with changes off the pitch as well.
He added: ‘Mum and boy are both doing well, although I didn’t get much sleep in the build-up to Bury.
‘It was a blessing in disguise it was an away game. I could get on that coach and shut my eyes!
‘We named him Frankie and I cannot speak highly enough of the way the gaffer has been with me as well.
‘We had some really rough times with the pregnancy. I had three or four days in the hospital and he rang me every day, texted me every day and was very good about it.’
