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.

6. Jacob Ramsey - Aston Villa
Another player who spent last term at Doncaster. The 19-year-old scored three goals in just seven appearances after moving to the Keepmoat in January, with boss Darren Moore saying Donny fans only saw a ‘snapshot’ of the midfielder’s ability. Photo: Alex Burstow
7. Ryan Giles - Wolves
Who can forget his screamer he scored for Shrewsbury in Pompey’s opening-day defeat at New Meadow last season?! Giles featured 25 times for the Shrews before he returned to Wolves and then joined Coventry for the second half of the campaign - but made just one appearance. However, the versatile left-sided talent, 20, can clearly make the grade in League One. Photo: Simon Davies
8. Matt Smith- Manchester City
The midfielder had a fairly frustrating 2019-20, having his loan spell at QPR cut short before featuring twice for Charlton and not having his deal extended beyond June 30. Nevertheless, the 20-year-old is a senior Wales international and may be open to dropping to League One for regular minutes. Photo: Michael Regan
