Danny Cowley is keen to bolster his options at the top end of the pitch during his Blues overhaul.
As things stand, Pompey have only two number nines under contract for the upcoming 2021-22 season in John Marquis and Ellis Harrison.
Jordy Hiwula was released at the end of his contract, having scored three goals in 15 appearances.
It's understood Cowley ideally would like to bring a target man to PO4 who can play alongside Marquis.
Joe Pigott’s one forward who is on Pompey’s shopping list after confirming his departure from AFC Wimbledon.
However, the Blues are braced to miss out on the man who plundered 22 goals this season, with Championship clubs interested.
But who else could Pompey look to target?
We’ve taken a look at who might fit the bill. Scroll down and click through the pages to see who’s on the list...
9. Maxime Biamou - free agent
The Frenchman was part of Coventry's journey from League Two to the Championship, helping them win two promotions. Biamou played 36 times in the third tier this seaso, scoring six goals but has been released at the end of his contract. Not a prolific goalscorer but works well with a partner. Photo: Tony Marshall
10. Devante Cole - free agent
The son of former Pompey striker, Andy, has had a nomadic career. However, Cole enjoyed a decent campaign with Motherwell, netting 12 times in 31 games. He's yet to sign a new deal at the Scottish Premiership outfit and has scored goals at League One level in the past. Photo: Ian MacNicol
11. Paul Mullin - free agent
The Liverpudlian spearheaded Cambridge to League Two promotion this season, bagging a whopping 34 goals in 50 outings. Mullin's unsurprisingly weighing up his options as a free agent, with Rotherham, Plymouth and Bristol Rovers all linked. Photo: David Rogers
12. Amadou Bakayoko - free agent
The 6ft 4inch forward helped Coventry to the League One title in 2019-20. He was released at the end of his Sky Blues deal. Photo: Catherine Ivill
