If Scotland lose and finish with three points, there are a number of results they will need to look out for – they will want as many groups as possible with two teams finishing on fewer than three points.

In Group A, if Mexico beat the Czech Republic and South Korea beat South Africa, that would leave the team in third on one point.

The next best scenario would be a big South Africa win to leave South Korea in third with three points and a poor goal difference.

Wins for South Africa and the Czech Republic would spell bad news for Scotland, leaving the third-place finisher on four points.

One of the few games that take place before Scotland face Brazil that has a bearing on where Scotland could finish comes in Group B.

Bosnia-Herzegovina and Qatar meet three hours before Scotland play and, if they draw, both sides will have two points.

Scotland would also want group winners the USA to at least get a point against Turkey, to keep them out of the equation.

On we go to Group E.

Ecuador and Curacao have one point apiece and play Germany and Ivory Coast respectively. Failure to win would mean whoever finishes third cannot better Scotland’s tally of three points.

In Group F, Scotland will be hoping second-placed Japan beat third-placed Sweden convincingly. A point for Sweden, though, would leave the third-placed finishers on at least four points.

The key fixture in Group G as far as Scotland are concerned is Egypt v Iran. A win for Egypt will ensure the team finishing third will have fewer than three points.

It is the same situation in Group H where Scotland fans will be rooting for Spain to beat Uruguay so the third-placed team can only finish on two points, while in Group I, a draw between Senegal and Iraq would mean the team in third will have just one point.

In Group J, Austria and Algeria are second and third respectively on three points and play each other in their final group game, so the scenario Scotland would want to avoid is that game ending in a draw. They would also want Argentina to avoid defeat against Jordan, who currently have zero points.

DR Congo and Uzbekistan are vying for third place in Group K.

A win for Uzbekistan would give them three points but, with a goal difference of -7, they would need a big win against DR Congo and for Scotland to lose badly to move above them in the standings.

In Group L, a point or more for Croatia against Ghana could be bad news for Scotland as it would again leave the third-place finishers with four points.

A big win for Ghana, and Panama not beating England, would be Scotland’s ideal scenario from a mathematical point of view.
