If Scotland loses its final group match against Hungary, it will finish fourth and be eliminated.
A draw would see Scotland finish third in the group and still have a chance of qualifying, but this will depend on results in other groups.
If Scotland wins the game, they will finish either second or third, depending on the result of Switzerland’s game against Germany.
Since Scotland drew with Switzerland, their rankings will be decided first on the basis of overall goal difference, then total goals scored, then disciplinary points and finally their ranking in the European qualifiers.
Scotland currently has a goal difference six goals worse than Switzerland, so a significant turnaround would be necessary in the final round of matches.
