Wigan head south knowing they can secure automatic promotion – and perhaps even the League One title – at Fratton Park.
But Danny Cowley is more concerned with making sure his own side can maintain their excellent home form.
Pompey are looking to extend their unbeaten record on the south coast to 10 matches, having not lost since the end of January.
He has praised the Latics for their success, though, and is looking forward to seeing Jack Whatmough and Tom Naylor return.
The Blues boss: “It’s a great test for us against a side who are top of the division and also have the best away record.
“But we’ve done well with this group for a sustained period of time and our home form has been very good.
“We welcome back both Jack and Tom, who are both really good players, as well as being great characters.
“I only worked with them for a short amount of time, but thoroughly enjoyed that period and they’ve both had consistent seasons, which doesn’t surprise me at all.
"We’ve done well with this group for a sustained period of time and our home has been very good."
“It’s a good story with Wigan because what occurred in the 2019/20 season when they got relegated from the Championship just shouldn’t be allowed to happen in football.
“But they’ve now got new owners, have recruited really well and now find themselves a point away from getting back there.
“We’ve scored consistently at home and have the fourth best record in the division, though, so we want to finish the season at Fratton Park with a positive result.”
Saturday’s comfortable victory over Gillingham saw Ronan Curtis bag a brace to reach a half-century of Pompey goals.
Cowley said: “It’s an excellent achievement when you consider that he’s mostly a wide player and he’s someone who gives his all for the team.
“Ronan is very competitive and robust, while he always carries a goal threat and his assists have gone up considerably.”
Connor Ogilvie limped from the field against his former club in the second half, but could be back to face Wigan.
Cowley said: “We’re hoping that he’ll be available. He just felt a bit of tightness in his hamstring, but there’s no strain there.
“It settled down and he was with us on Monday morning, so fingers crossed that he’ll be able to feature.”
