League One rivals MK Dons provide the opposition after Tuesday’s FA Cup success at Ipswich Town.
There’s plenty for Danny Cowley to consider as he weighs up his starting XI for the clash.
Cowley will judge who needs minutes after the 2-0 win at Portman Road, after making seven switches from the 0-0 draw at Derby.
There’s also the debate about whether Dane Scarlett or Owen Dale are given permission by their parent clubs to feature.
With the FA Cup allowing nine subs, that opens the debate about who gets to fill those positions for the Blues.
Here’s how we think Pompey will line up.

10. CF: Joe Pigott
Missed out against his old side on Tuesday, as part of the terms of his loan move - but will be pushing hard for a Cup start, especially if Scarlett doesn't get clearance to play. Photo: Jason Brown
11. CF: Colby Bishop

12. Sub 1: Josh Oluwayemi
Keeper really impressed in the Trophy on Tuesday night, where his starts have largely arrived. Chances are it's a place back on the bench tomorrow, however. Photo: Simon Davies
