A quick look at the pompey website reveals thy have yet to sell out in their sections
Pompey still have a "few" tickets available in some areas for the game but seem to be struggling to sell the hospitality packages,, for £150 you can have the full monte and they even throw in a second match of your choice into the equation, but if thats a bit steep for you then why not go for a seat in the directorrs box a snip at a mere £80 or if you after something a bit cheaper still, then there are plenty of seats available in the Executive seats at only £50.
Whether you have to have proof of supporting Pompey is another matter, but if your after watching the game in style (or as much of it as you can do, although this is Xmas so Victorian style is all the rage) then here could be a chance for you to do so.
