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...
9. Fleetwood - Callum Camps
The midfielder is surely in line to be named player of the season at the Cod Army. Since arriving at Rochdale last summer, Camps has scored eight goals. Photo: Daniel Chesterton
10. Hull - Mallik Wilks
The powerful forward has been a vital cog in the Tigers' promotion push, scoring 14 times so far. Also isn't afraid to do the dirty side of the things - as we saw in Hull's 4-0 win at Fratton Park. Photo: George Wood
11. Jack Tucker
The 21-year-old centre-back has played 34 times in all competitions for the Gills this season. Manager Steve Evans admitted there was interest in the defender in January and he'll surely be wanted again this summer. Photo: James Chance
12. Ipswich - Marc McGuinness
The on-loan Arsenal centre-back has been one of the Tractor Boys' best performers this season. Statistically, the 20-year-old has won more aerial duels than Sean Raggett. He'll surely be playing higher up the pyramid next season. Photo: Nathan Stirk
