Colby Bishop is currently the only contracted front man beyond the end of the season, with Joe Pigott and Dane Scarlett to return to Ipswich and Spurs respectively when their deals come to a close.
Last summer saw Danny Cowley splash the cash for the 26-year-old from Accrington and the forward has repaid the Blues by netting 19 goals to date.
With the play-offs an unrealistic target for Pompey, John Mousinho will have one eye on the upcoming window and could be looking to splash the cash to improve his side.
And the head coach has previously stated he will be eyeing reinforcement into his attacking department.
We’ve chosen 12 strikers from the Championship to League Two who could tick the box for the Blues in the summer.
9. Josh Gordon - Barrow
The 28-year-old is a handful for defenders and is Barrow’s top scorer this term, netting 11 goals this season in League Two. He does have League One experience, featuring for Walsall during their relegation campaign, which saw him appear on the scoresheet on eight occasions. Photo: Pete Norton
10. Niall Ennis - Plymouth
Ennis is out of contract at Plymouth in the summer and has been in fine form this season, impressing for the promotion hopefuls. He’s bettered his tally in front of goal, appearing nine times on the scoresheet League One to date. The 23-year-old can also play on the left and in a number 10 role and it remains to be seen where his future lies should the Pilgrims secure promotion. Photo: Pete Norton
11. Josh Davison - AFC Wimbledon
The 22-year-old made the drop to AFC Wimbledon last summer and has impressed in League Two. This has seen him net nine goals in 35 league outings to date and brings an aerial threat in the box. He penned a three-year deal at Plough Lane last summer. Photo: Alex Davidson
