John Mousinho’s side face an in-form side at Stadium MK, with Mark Jackson overseeing an upturn in fortunes to drag his side away from the drop zone.
Pompey need to keep their impressive form under the new boss going, however, to up the pressure on the top six.
They have players coming back into the equation for the clash – here’s how we think they will line up.
17. SUB - Michael Jacobs
Could count himself hard done by not to start after looking the most likely to break down Forest Green last weekend. Hackett's extra mobility may be favoured away from home, however, though a move to a 4-2-3-1 could offer an alternate route into the starting XI. Photo: Jason Brown
18. SUB Dane Scarlett
What an option to have off the bench. The Spurs loanee could be a potential game changer, if required. Photo: Jason Brown
19. SUB Joe Pigott
Had momentum before his red card at Accrington after two starts on the spin. Most likely to start on the bench, though, don't totally write off being used behind Colby Bishop. Photo: Simon Davies
