In any case, there weren’t that many left when I looked yesterday - only availability of any real note was up in the gods in East Stand Level 3 plus in the 2 blocks Saints didn’t take up. Oh, and some at the front of the North Stand. Otherwise it was the usual single seats dotted about.
This game - midweek at the back end of November - was always going to sell slower than most other games so I don’t see what the issue is. There’s hardly anything left for West Ham on Sunday and the same goes for Bournemouth on Dec 23rd and that’s a notorious time for some fans to sack the game off to go Christmas shopping.
