From the goalkeeping department up to the strikers, there’s strength in depth in every position and it's a key reason why the Blues sit fourth in the table.
However, there is always room for improvement.
Pompey are always looking how they can bolster their set-up to progress their quest up the football pyramid.
Already, Kenny Jackett and his recruitment team will be putting together early plans for the summer window – despite the manager's contract still unsettled.
Whether the Blues achieve promotion to the Championship or not, signing players in League One this season is always a useful starting point.
And we have picked out one player from all 23 of Pompey’s rivals who would improve the current squad...
13. Lincoln - Jorge Grant
The ex-Nottingham Forest midfielder will surely be named in the Team of the Season, having inspired Lincoln's shock automatic promotion push. Grant has racked up a brillaint tally of nine goals and seven assists this term. Photo: James Chance
14. MK Dons - Scott Fraser

15. Northampton - Peter Kioso

16. Oxford - Cameron Brannagan
The U's captain signed a new deal last summer having attracted potential suitors. However, there is a buy-out clause in his contract and he will surely want to test himself in the Championship sooner rather than later. Photo: Catherine Ivill
