Pompey have proven their calibre in cup competitions so far this season, but now they are looking for a run of league wins.
A midweek draw with Burton means there has been just one three-point haul from the opening six fixtures.
And Kenny Jackett’s side will be looking to improve that statistic when they visit Wycombe at the weekend.
But they will not be expecting an easy test against a Chairboys side currently sitting in third spot, albeit having played three games more.
Defeat at Gillingham last Saturday was the first they have suffered in League One, while they also exited the Carabao Cup to Reading on penalties in the first round.
Matches at Adams Park have resulted in victories over Bolton (2-0), MK Dons (3-2), Southend (4-3) and Lincoln (3-1), as well as Tuesday’s night Accrington stalemate.
That win against the Shrimpers was particularly memorable, as Gareth Ainsworth’s men were trailing when the game entered the 89th minute.
Pompey enjoyed success on their last visit to Wycombe back in April, with Brett Pitman’s brace and a Jamal Lowe strike sealing a 3-2 triumph.
Pompey are still missing the injured quartet of Lee Brown (Achilles), Marcus Harness (thigh), Bryn Morris (groin) and Jack Whatmough (knee).
Wycombe will be without Paul Smyth and Alex Samuel, while Rolando Aarons faces a late fitness test.
