The unwashed and their IRA/sky fairy songbook can make the most of a full Roseburn as it will never happen again for league matches. If anything you'll be pumped down to one section from next season - and even then with how segregation is laid out, it's not even a full section.
As for the game, if Neilson hasn't learned a single thing from the recent shoeing at home to the Buns, and doesn't flood the midfield then I don't know what to tell you, tbqh. Realistically, the 3-4-3 needs binned for games against the Old Firm and in Europe. Devlin and Grant or Halliday must start with Snodgrass as a minimum. Frankly, you could even play the four of them. McKay can stay on the bench or at home for this one.
