It's a tough assignment for John Mousinho's side against opposition with one of the best home records in the division.
The Blues are on a nine-game unbeaten run, however, as they aim to move a step closer to the Championship.
Here's how we think Pompey will line up, as they embark on the run-in with 10 games remaining.

10. ACM Callum Lang
Could use Peart-Harris in the central attacking role, but no obvious reason not to go with the impressive January arrival there at Bloomfield Road. | PA
11. LW Paddy Lane
Got three more games before we lose one of the big standouts of the season against Barnsley - hopefully time for some more goals and assists. | Jason Brown/ProSportsImages
12. ST Colby Bishop
Sixteen for the season, but one goal in five for Bishop now with Yengi breathing down his neck. Quite a close call. Photo: Jason Brown
