With wage levels expected to drop as a consequence, clubs are also expected to struggle to retain some of their best players, with some eye-catching performers potentially up for grabs.
We’ve contacted local journalists covering League One to compile a list of each club’s free agents this summer – and here are the prominent names which may well interest Pompey...
13. Charlie Wyke (striker)
Wyke has been a free-scoring centre-forward at Carlisle, Bradford and now Sunderland, wreaking chaos which his physicality and strength in the air. He has plundered 30 goals for Sunderland this season, yet is waiting to be offered a new deal. Picture: Justin Setterfield/Getty Images Photo: Justin Setterfield
14. Gwion Edwards (winger)
The Welshman was recruited from Peterborough for £700,000 two years ago and established himself at Ipswich as a highly-effective winger. The 28-year-old has been hit by injuries at times, but still made 37 appearances for the Tractor Boys this season, scoring five times. Picture: Lewis Storey/Getty Images Photo: Lewis Storey
