The pot 1 ship appears to have sailed. That would require a Georgia win in Spain on Sunday. Not going to happen.
Pot 2 is still on but that will require a two-goal Scotland win over Norway at Hampden on Sunday or a big single-goal success; a 4-3 sort of thing.
Anything else and it's pot 3...
There is a school of thought, mind, that pot 3 is actually the better place to be.
All the arithmetic, done by someone far sharper than us, is here.
