The Blues have outlined their disapproval for the introduction of salary caps ahead of the 2020-21 season.
The potential implementation would enforce a £2.5m per year wage restriction on League One sides ahead of the new campaign.
Pompey’s current wage bill is understood to be around £4m.
Mark Catlin has branded the concept ‘an absolute disgrace’ and pinpointed that the Blues will have to slash their wage bill and operate with the same salary cap as clubs recording substantial losses.
