Kollade upp FIFA:s regler och det finns ett dokument (Regulations - 2018 FIFA World Cup Russia) som kan laddas ner. På sida 42 finns följande text under ”32 - Group stage”.
Och det innebär att jag förstår ännu mindre vad olika tidningar skriver om Sveriges chanser att gå vidare, t ex att "bara" vinna över Mexiko oavsett hur många mål Sverige gör mot Mexiko (Mexiko har +2 i målskillnad in all group matches, Sverige och Tyskland har 0 in all group matches)

5. The ranking of each team in each group shall be determined as follows:

a) greatest number of points obtained in all group matches;
b) goal difference in all group matches;
c) greatest number of goals scored in all group matches.

If two or more teams are equal on the basis of the above three criteria, their rankings shall be determined as follows:

d) greatest number of points obtained in the group matches between the teams concerned;
e) goal difference resulting from the group matches between the teams concerned;
f) greater number of goals scored in all group matches between the teams concerned;
g) greater number of points obtained in the fair play conduct of the teams based on yellow and red cards received in all group matches as follows:

– yellow card: minus 1 point – indirect red card: minus 3 points (as a result of a second yellow card) – direct red card: minus 4 points – yellow card and direct red card: minus 5 points

Only one of the above deductions shall be applied to a player in a single match;
h) drawing of lots by FIFA.
