Pompey still have 1,700 tickets left for next month’s south coast derby.
Southampton visit Fratton Park on Sunday, December 18.
But while the Fratton end is sold out, there are seats available in other home ends of the ground.
Despite tickets going on general sale eight days ago, 1,700 still remain.
In particular, there are still empty seats in the North stand (upper wings) and in the D section of the South stand.
Tickets for these areas are priced at £30 for adults, £22 for seniors/young persons and £15 for juniors.
However, only one ticket can be purchased per person.
Elsewhere, the Milton end has been allocated to Southampton fans.
A total of 3,200 tickets are being made available to the visiting supporters by ballot.
Meanwhile, tickets in the Family Enclosure are also available.
These are priced at £25 for adults, £15 for seniors/young persons and £10 for juniors.
Such seats cannot be bought on-line and adults must be accompanied by a junior.
For any seat in the ground, a purchasing supporter must have been registered on the club’s database since last season or earlier.
To ensure the club’s database, including your record of attendance, is up-to-date, please have your details – along with those of people you may be buying tickets for – with you when purchasing tickets.
Tickets can be bought from the club website portsmouthfc.co.uk
They can also be obtained by calling 0844 847 1898 (option one) or in person from the Frogmore Road ticket office.
The fixture kicks off at 1pm and is also being televised live on the BBC.
