The left-back made a superb impact during the second half of the season while on loan at Fratton Park.
Seddon’s attacking displays and set-piece deliveries saw him quickly establish himself as a fans’ favourite.
In total, he scored one goal in 18 appearances for Kenny Jackett’s side.
Supporters certainly would relish the chance of seeing the 22-year-old return to the south coast next campaign.
That was Pompey’s plan before the coronavirus crisis, with Seddon admitting he wanted a permanent home somewhere after seeing opportunities limited at St Andrew’s.
However, it’s understood that, at present, there’s little chance the Blues will be able to stump up the fee that would be required to prise him back to PO4.
Pompey are feeling the impact of the Covid-19 crisis – just like most other clubs in England.
They are looking at a gaping hole in their budget with fans, at best, likely to be restricted in the numbers who can attend home games for a significant part of the 2020-21 campaign
There is also the issue of a wage cap being introduced, with League One clubs likely to be operating with a £2.5m player salary limit.
What’s more, Pompey have previously been wary of the Championship side placing an inflated valuation on Seddon given his impressive displays.
The Reading-born ace has a year remaining on his Brum deal, although the club hold the option for an additional 12 months.
The Blues’ situation could change if do sell one of their prized assets, although Jackett has previously said there is no pressure to.
Even so, Seddon may get an opportunity under the next manager that takes charge at Birmingham following the resignation of Pep Clotet.
A berth in their defence could open up should Kristian Pedersen attract interest once again.
Jackett appears to be in the market for a left-back, with no senior option currently under contract.
Lee Brown is in discussions over extending his stay, although Brandon Haunstrup has rejected a new deal and looks set to join Kilmarnock.
