Nigeria and Iran could see their World Cup fate decided by the drawing of lots.
Argentina play Nigeria and Iran face Bosnia-Herzegovina in Group F's final matches on Wednesday, and if Argentina and Iran were both to win their games by the same one-goal margin then the FIFA Organising Committee would need to draw lots to determine whether the Super Eagles or Team Melli would advance.
Iran and Nigeria drew 0-0 in their opening match, with Iran then losing 1-0 to Argentina and Nigeria beating Bosnia-Herzegovina 1-0 in their second games.
FIFA rules determine that teams should be separated first by points, then goal difference, then goals scored and then their head-to-head record. However, lots are used as a last recourse if they cannot otherwise be set apart.
The Rule
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;
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
