After a September full of points, Pompey left it late to ensure that October started with victory over Wycombe earlier in the week.
Now they will be looking for a similar result – preferably in a more comfortable fashion – when Port Vale visit Fratton Park on Saturday (3pm kick-off).
Their opponents endured a miserable second half to last season to ultimately finish just three places above the drop zone.
That saw boss Darrell Clarke lose his job, with interim replacement Andy Crosby handed the reins on a permanent basis over the summer.
Fears that poor form would seep into the current campaign proved correct when his side were thrashed 7-0 at Barnsley on the opening day.
But the Valiants quickly brushed off that humbling, losing just one of the next eight games to get fans instead dreaming of a promotion push.
They have stuttered slightly over the past week, though, and head south on the back of consecutive defeats to Bolton and Bristol Rovers.
Attention might also be diverted by a run in the Carabao Cup, as a win at fourth tier Mansfield at the end of the month would see Port Vale progress to the quarter-finals.
Pompey fought from two goals down and a missed penalty in this fixture last term, with Colby Bishop and Michael Jacobs scoring to earn a draw.
TEAM NEWS
Josh Dockerill (knee), Tom Lowery (knee), Marlon Pack (ankle) and Anthony Scully (knee) are all sidelined.
Regan Poole and Alex Robertson also miss out for Pompey, with both collecting a fifth booking of the season on Tuesday to earn a one-match ban.
There are also doubts over the fitness of Connor Ogilvie (groin), but Kusini Yengi is available again after recovering from an ankle problem.
Port Vale will be without defender Jesse Debrah following his red card at Bristol Rovers earlier in the week.
Striker Ryan Loft is missing with a calf problem, but the club have brought in free agent Uche Ikpeazu to boost their attacking options.
