Pompey have seen the gap to the drop zone cut from 10 to four points, as Valerien Ismael’s side arrive at PO4.
So it’s a big home clash for the Blues, with big calls for John Mousinho to as he welcomes new boy Alex Milosevic and fit-again pair Jordan Williams and Christian Saydee to his options. There’s no Kusini Yengi, however, with the striker starting at Deepdale last time out.
We’ve considered personnel and formation - and this is how we think Pompey will line up against Rovers.

Dropped to the bench at Preston after looking a little jaded. No excuses not to be refreshed and ready to go at full throttle again now. | National World
10. ACM Adil Aouchiche
More effective in the middle, which is where you'd suspect the Sunderland loanee will operate from this weekend. | Getty Images
11. LW Josh Murphy
The charge towards player-of-the-season plaudits has to continue now for winger, who's been Pompey's standout attacking threat this term. | Graham Hunt/ProSportsImages
12. CF Colby Bishop
Not as effective when asked to play deeper, so expect the Magic Man to return to more orthodox number nine role this weekend. | National World
