League One sides could be restricted to a £2.5m wage ceiling for the 2020-21 campaign and limited to 22 senior players.
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.

13. Bobby Duncan - Fiorentina
The striker who broke Pompey Academy's hearts when netting a late-winner for Liverpool in the FA Youth Cup in 2018. It hasn't exactly gone to plan for the 19-year-old since he left for Italy and was linked to Sunderland in January. Photo: Jan Kruger
14. Anthony Driscoll-Glennon - Burnley
The Clarets’ under-23s skipper joined Grimsby on loan in January and made 12 outings and scored once before the season was suspended. The 20-year-old may be looking to climb up the pyramid and a switch to Pompey could suit with a left-back needed. Photo: Steve Robards
15. Timothy Eyoma
Someone who Kenny Jackett may remember during his short stint working in Spurs’ academy. Eyoma helped England under-17s win the World Cup in 2017 and made his Tottenham debut in January 2019. He joined Lincoln on loan in late January but didn’t make an appearance before the season was suspended. The 20-year-old may want first-team football. Photo: Jan Kruger
16. Dujon Sterling - Chelsea
The defender, 20, was a regular starter for Coventry during 2018-19. He joined Wigan last summer but only managed 10 appearances before returning to Chelsea. He has League One experience if Pompey want another right-back to potentially send Haji Mnoga out on loan. Photo: Nigel French
