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.
But how do the other teams confirmed to be in League One next term feel about a salary cap?
We've taken a look at what’s been said...
1. AFC Wimbledon
Maneger Glyn Hodges recently told his club's website that 'we are building a stadium at the moment, so a lot of the finances have been geared to that'. That means they'll likely be in support of a salary cap. Photo: Alex Burstow

Owner Simon Sadlier told the Guardian last month that ‘football needs to change or else we’re going to lose it’ and is in support of a wage cap being brought in. The Seasiders have already been proactive in the transfer window, signing Keshi Anderson, Oliver Sarkic and Marvin Ekpiteta on frees. Photo: Richard Sellers
3. Bristol Rovers
Bristol Live reports Rovers 'are in favour of wage control' and that they have faith that manager Ben Gardner can improve the players that he will be working with on the training ground. Photo: Pete Norton
4. Burton
Considering the cost-cutting measures the Brewers have been putting in place - with manager Nigel Clough standing down the most significant - it’s likely that they will be in favour of a salary cap. Photo: Daniel Chesterton
