Here is the rule for the ranking of the teams in the Group Stage of the World Cup, from Article 41 of the Regulations, 2014 FIFA World Cup Brazil (PDF):
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) drawing of lots by the FIFA Organising Committee.
Can someone explain me what "between the teams concerned" means in item d), e), f) ?
