It will arguably be Pompey’s toughest test of the 2017/18 campaign on Easter Monday.
They host a Wigan side who are currently topping the League One table and stunned Manchester City to reach the FA Cup quarter-finals.
Paul Cook will want his troops to continue their title charge when he returns to Fratton Park for the first time since departing last summer.
But his replacement Kenny Jackett does not want to expend too much energy worrying about the opposition.
The Blues boss said: “It was always going to be a good game whoever we were facing because of the position we’re in.
“Now it’s up to us to put on the kind of performance that we know we’re capable of to get the crowd behind us.
"All of my concentration will be on my own team and there should be a terrific atmosphere."
“Wigan have got real quality. We understand that and fully respect everything they’ve done this season – both in the league and FA Cup.
“They’ve obviously got a lot to go for themselves, but it’s more about us doing our best and playing to our maximum.
“It’s three wins on the spin and those results have come just at the right time, giving us an opportunity of getting into the top six.
“So all of my concentration will be on my own team and there should be a terrific atmosphere – as there always is with Pompey.
“We need the win to keep driving forward, with both fifth and sixth spot in the table very much still open for us.”
Wigan have had an extra day to prepare for the contest after beating Oldham on Good Friday, but Jackett does not want that to be used as an excuse.
He said: “It’s all between your ears – if you tell yourself that you’re tired, then you will be.
“Our preparation will be professional. We’re looking forward to the game and we’ll certainly be ready for it.”
