Pompey make the long trip north for a second successive weekend when they visit Wigan on Saturday (3pm kick-off).
Danny Cowley’s side saw their 100 per cent winning record ended by a goalless draw at Doncaster last time out.
But another shut-out means the Blues are one of just two sides – along with League One leaders Sheffield Wednesday – yet to concede in the entire EFL.
Their next opponents were beaten at Sunderland on the opening day, but have gone on to enjoy win over Rotherham and Charlton, as well as a draw with Wycombe.
Leam Richardson’s troops also beat both Hull and Bolton to reach the third round of the Carabao Cup, where they will lock horns with the Black Cats once more.
Wigan exited administration towards the end of last season and survived the drop by just a single point.
And they have worked hard to revamp their squad over the summer, with 13 new players coming through the door.
Both sides won on each other’s patch during the 2020/21 campaign, as a strike from substitute Andy Cannon was enough to secure Pompey the points at the DW Stadium on Easter Monday.
TEAM NEWS
Pompey are sweating over the fitness of Marcus Harness (quad), while Jayden Reid (knee) and Liam Vincent (shin) are definitely missing.
Tom Naylor and Jack Whatmough are both expected to feature against their former club for Wigan, who could hand a debut to Tom Bayliss.
