However, players under 21 will be exempt and chief executive Mark Catlin admitted that’s where the Blues may have to focus their recruitment if there is a salary cap.
He said: ‘Although with under-21s exempt, we’ll have to focus heavily on the under-21 market – and will adapt our market accordingly.’
If that is the case then it’ll be crucial Pompey sign youngsters who will be ready for the demands of League One football.
We’ve picked out the players that could suit Kenny Jackett's side…
1. Callum Morton - West Brom
The striker stole the show in the League Two play-offs for Northampton. He was immense in the second-leg win over Cheltenham and in the 4-0 victory against Exeter in the Wembley final. In total, the 19-year-old scored eight goals in 12 outings for the Cobblers.They’ll want him back but Pompey would be a more attractive option should they be interested. Photo: David Rogers
2. Lewis Gibson - Everton
The centre-back joined Fleetwood in January and was a regular during their failed play-off bid, playing 14 games in total. Gibson, 20, is reportedly set to head out on loan against for the upcoming campaign. He’s a left-footed centre-half which would be ideal for Pompey and has represented England at under-20 level.

3. Alex Cochrane - Brighton
A player that readers have heard quite a bit about lately. The left-back is on Pompey’s radar and Brighton are keen to get him out on loan. He’s an England under-20 international who’s highly regarded at the Amex. Photo: Alex Burstow
4. Cameron John
The centre-back scored three goals in 21 appearances while on loan at Doncaster during the 2019-20 campaign. Also capable of playing left-back, the 20-year-old recently had his deal at Wolves extended and they could look to get him out for more experience. Photo: Alex Burstow
