Can Scotland do it? Will Scotland do it? If they do, who will they play in the play-offs?
There are many ifs and maybes as the Scots face group winners Spain looking for a sequence of results that will leave them ahead of the Czech Republic, who take on Lithuania, as runners-up in Euro 2012 qualifying Group I. Craig Levein's side are a point ahead of the Czechs, who will qualify because of a better head-to-head record should the two sides finish level on points.
While the winners of the nine groups qualify automatically for the finals in Ukraine and Poland, the teams that finish second will have to go through another home and away tie against one of the other second-placed teams to claim a spot at the finals.
The best runners-up of the nine groups also qualify automatically. That position at the moment looks like going to Sweden, who are currently second in Group E. If Sweden beat the Netherlands, who have already qualified as group winners, they qualify directly.
Germany qualify as winners. The battle is between Belgium and Turkey for second place. Belgium have one point more going into the final game. Belgium only have to match their rivals' result in their final group games. Belgium are away to Germany, while Turkey play host to Azerbaijan.
Russia only need a draw against Andorra to qualify as group winners. The Republic of Ireland are second, one point above Armenia and the sides meet in Dublin. A draw will be enough to put the Irish in the play-off spot.
Italy have qualified as group winners. Estonia currently sit second having completed their qualifying matches. Serbia are one point behind Estonia, but if Serbia beat Slovenia, they will pip Estonia for the play-off place.
France are top by one point from Bosnia and Herzegovina. The teams meet in Paris, where a draw will see France qualify as winners while Bosnia and Herzegovina are guaranteed at least a play-off spot.
Greece have a two-point lead over Croatia going into the final group games. Greece need a point in Georgia to secure first place regardless of Croatia's result against Latvia. However, Croatia still have the possibility of finishing as best runners-up on goal difference with a victory should Sweden fail to win, there is not a draw between Denmark and Portugal and Russia do not lose to Andorra and finish second in their pool.
England have qualified, while Montenegro have finished second to guarantee their first-ever play-off spot.
Portugal and Denmark are level on points at the top and they meet in Copenhagen. A draw will see Portugal qualify as group winners and possibly put Denmark through as best runners-up providing Sweden do not beat the Netherlands. Norway, who are three points behind in third, have an outside chance of finishing second.
So possible opponents for Scotland in a play-off are Belgium, Turkey, Republic of Ireland, Armenia, Estonia, Serbia, France, Bosnia and Herzegovina, Greece, Croatia, Montenegro, Portugal, Denmark and Sweden.
The draw for the play-offs will take place on Thursday 13 October.
These eight sides will be divided in two pots containing four seeded and four unseeded teams respectively, in accordance with the national team coefficients established at the conclusion of the group stage.
The first leg of the play-off ties are scheduled for 11 or 12 November, with the second leg on 15 November.
