Simon Eastwood has targeted an extended run in the Pompey side after retaining his place between the sticks.
The Blues goalkeeper made his League One debut for the club in last night’s 1-0 reverse to Brentford after ousting Mikkel Andersen.
The on-loan Reading keeper was unavailable for the FA Cup defeat to Notts County at the weekend, which opened the door for Eastwood.
And the glovesman impressed boss Michael Appleton enough in that game to hang on to the shirt.
Eastwood said: ‘It would be nice to have a run in the side.
‘Results haven’t gone our way in these two games but when I have come in, I don’t think I have really done anything wrong. That’s all I can do, really.
‘I’m mates with Mikkel and obviously he will be gutted that he was dropped but that’s how it happens.
‘It has happened to me in the past and I’m sure it will happen to me again.
‘The main thing is not to sulk and he didn’t so that’s fair enough.
‘I’ve been working hard to get the number-one spot over the past couple of months.
‘Although it was a disappointing result, I was happy to keep my place.
‘Hopefully I can do that in the coming weeks.’
Eastwood was powerless to prevent Clayton Donaldson’s early winner after the Blues defence failed to deal with a routine set-piece.
The Brentford striker’s clever header then left the keeper stranded and unable to recover in time.
Eastwood explained: ‘The ball travelled a long way and nobody headed it away.
‘The defensive line started quite high and they all admitted they then dropped too deep.
‘As a keeper, you have to follow the path of the ball because you’d look pretty silly if it just went straight in.
‘It’s hard if you have people running across your vision, but he made a good contact and it was just too far to get the other way in time.’
