How to group the World Cup?

First, the goal difference, then the number of goals, then the relationship between victory and defeat, and finally the draw.

The 32 teams participating in this tournament are divided into eight groups by drawing lots, and the top two in each group are qualified to continue to participate in the second stage of the competition (elimination system).

In the first stage of the group stage, the single round robin system was adopted, and each team scored 3 points for winning one game, 0 points for drawing one game 1 point, and 0 points for losing one game. At the end of all the group matches, the first factor that determines the ranking of each group is the score obtained by each team in all three group matches. In the case of the same score, the team with more goal difference (the total number of goals scored MINUS the total number of goals conceded) ranks in the top. If the goal difference is still the same, the team with more goals will rank in the top.

If the above three criteria are still not ranked, it is necessary to look at the game points, goal difference and total goals of the relevant teams in turn (the above three criteria cannot be divided into two or three teams). In other words, if the two teams are confused, it depends on the winning and losing relationship between the two sides; If the three teams can't tell the order, draw out the fourth team and their fighting results (* * * three games), and then compare the points, goal difference and total goals of the three teams in the three games.

If you still can't tell the order, you can only draw lots to decide the group ranking.

England, Ireland, the Netherlands and Egypt are in the same group, and Egypt has become an important weight on the balance of this group. Except for the 0-/kloc-0-0 loss to England, the other five games in this group were all draws. As a result, England was the first to qualify, Egypt was the bottom, and Ireland and the Netherlands had exactly the same points, goal difference and goals conceded. As a result, the two teams can only draw lots to decide the ranking. Finally, Holland saw the next signing, and the third place was the result.

It can be seen that if the score is the same as the winning goal, the qualifying can only be decided by drawing lots.
