Alex Bass is hoping to take advantage of Craig MacGillivray’s first Scotland call-up.
With Pompey’s number one otherwise engaged, it leaves a vacant spot for Tuesday evening’s Leasing.com Trophy clash with Crawley.
Bass is likely to take his place in the team, having been on the bench for every other game so far this season.
And he has learnt a lot from working with MacGillivray and fellow stopper Luke McGee on the training pitch.
The 21-year-old said: “It would be a good experience for me to get out at Fratton Park again and play a game. I want to show the fans what I can do.
“I’ve been working hard for a good few years now and the more you train with senior keepers, the sharper you get.
"It would be a good experience for me to get out at Fratton Park again and play a game."
“Craig has been a bit of an inspiration for me. He came here having not played a huge amount of games and I can only dream of getting to where he is now.
“The process has been a long one, but hopefully I can see the rewards of that and repay the manager’s faith.”
Bass was an unused substitute when Pompey beat Sunderland back in March to win the competition last season.
He said: “The day out at Wembley was fantastic for us – and for everyone who’s involved with this club.
“It was a real highlight and so if we could do the same again this season, then it would be absolutely brilliant.
“We played a lot of young players in the early stages and the further we went, you more you realised we had a real chance.”
