Pompey know exactly what is required when they welcome Barnsley to Fratton Park this evening (7.45pm kick-off).
A draw for John Mousinho’s men would secure promotion with two games to spare, while a win seals the title.
But hoping to play the role of party poopers are opponents who still have plenty left to play for themselves.
The Reds knows that victory on the south coast would guarantee a play-off spot and an extension to their campaign.
A place in the top two for Neil Collins’ side appeared on the cards six weeks ago, only for them to concede a stoppage-time equaliser against Bolton at Oakwell.
They have gone on to win just two of the following eight fixtures and twice fought from behind to draw with Reading on home soil at the weekend.
That ended faint hopes of automatic promotion, but the Tykes will be hoping to go one better than last season.
They defeated Bolton over two legs in the play-offs, only to lose to Sheffield Wednesday when Josh Windass struck right at the end of extra-time.
This fixture last term finished 1-1, but the Blues came out on top when they headed to South Yorkshire earlier in the current campaign.
Pompey got off to a blistering start, with Paddy Lane, Colby Bishop and Connor Ogilvie all netting inside the opening 16 minutes of a 3-2 success.
TEAM NEWS
Terry Devlin (shoulder), Josh Dockerill (knee), Tom McIntyre (ankle), Joe Morrell (knee), Regan Poole (knee), Anthony Scully (ankle) and Alex Robertson (hamstring) are all out for the remainder of the season.
Robbie Cundy (glute) and Donovan Pines (thigh) are both missing for the visitors, who have doubts over the fitness of Jon Russell.
