Survival was secured by John Mousinho and his players with two games to spare, quite some achievement after stepping up to the level again after a 12-year absence.
It means there will be a party atmosphere as the Blues sign off at PO4, but the stakes are high for the visitors as they need to win to secure their place in the division.
Here’s how we think Pompey will line up for the lunchtime kick-off.

10. ACM Callum Lang
Okay, so a start on the final day may be a little ambitious, but if the view is Lang can do at least 45 minutes it's not inconceivable. If not Saydee could go through the middle with Scouser boosting things in the second half. The other option is to keep the formula at Hillsborough, with Dozzell more advanced. | Jason Brown
11. LW Josh Murphy
What a signing, what a season and what a player! Josh Murphy deserves all the appreciation he's going to get from the Fratton Faithful tomorrow. | Jason Brown/ProSportsImages
12. CF Colby Bishop
The race to be top scorer goes to the final day with Lang, but what a story this season has been for Bishop - one of the best tales in English football this term. Photo: Jason Brown
