But how does John Mousinho approach the game, as he goes in search of a massive three points in the bid to stay in the second tier?
Mousinho has indicated there will be changes for the meeting with John Eustace’s side - and this is how Pompey writer Jordan Cross thinks he will go.
5. CB Connor Ogilvie
Excellent once again at Coventry and now very much in the player of the season conversation. Could well be an argument to move Ogilvie to left-back for this one, in which case Marlon Pack would have to start in the middle. | Jason Brown/ProSportsImages
6. LB Cohen Bramall
Frustrated Mousinho with late and costly mistake on Wednesday, but the Pompey boss acknowledged it was a strong display otherwise from left-back. Close call whether he continues for this one. | National World
7. CM Freddie Potts
Looks nailed on to continue in the middle of the park for the rest of the campaign. | Jason Brown/ProSportsImages
8. CM Andre Dozzell
Playing a continuously decent level and looked sharp again at Coventry and effective with his passing both laterally and forwards. Photo: Jason Brown
