Pompey would welcome a similar outcome to their last away game when they visit Southend this weekend.
Although it might be better for the nerves of everyone if they do not leave it as late as witnessed at MK Dons last Saturday.
Their opponents are currently sitting 14th in the League One standings and are a comfortable seven points clear of the drop zone.
But it was a distinctly more worrying position when Phil Brown departed as manager midway through last month.
Former England international Chris Powell was named as his replacement and has yet to experience defeat in four games in charge.
He guided the Shrimpers to three successive victories – including over then leaders Wigan – before a goalless draw at Bury on Tuesday evening.
Pompey have lost on each of their four most recent visits to Roots Hall, with strikes from Gerry Creaney and Darryl Powell securing the last triumph back in 1994.
It was Kenny Jackett’s side who came out on top at Fratton Park earlier in the campaign, though, as Brett Pitman netted the only goal of the game.
Brandon Haunstrup and Jack Whatmough are both available for selection after coming through an in-house training game unscathed.
But the Blues are still without the injured trio of Stephen Henderson (thigh), Stuart O’Keefe (groin) and Danny Rose (leg).
Southend will be missing Rob Kiernan (knee), Ted Smith (shoulder), John White (ankle) and Anthony Wordsworth (calf), with Michael Kightly (hamstring) also a doubt.
