What are the requirements of the World Cup for the team?

According to the lottery principle announced by FIFA, the first important principle is that no two teams will be drawn into the same group on any continent except Europe. In other words, teams from South America, Central and North America, Africa or Asia will not meet teams from the same continent in the group stage, and European teams will not have three fees in the same group.

On February 6th, 65438, the organizing committee will decide eight seed teams by comprehensively considering the past record and FIFA world ranking. Eight seed teams will "take their places" in the lottery ceremony, and the host country Germany has decided to draw them into Group A in advance ... The remaining 24 teams will be divided into second, third and fourth files respectively, and the grouping method will ensure the "geographical balance principle" of each group. The lottery ceremony will draw teams from each file first, and then draw out the position of the team.

At present, the preliminary analysis opinions of major international media are consistent, that is, according to the previous rules, the Dutch team will not qualify as a seed team, and the eight seed teams are Germany, Brazil, Argentina, Italy, France, Spain, England and Mexico. On this basis, according to the "big principle" of the above grouping, we can predict a limited number of possible grading schemes.

1. Eight of the nine European teams except the seed team were included in the same file; Five African teams are in the same file as three Central and North American teams outside Mexico; Four Asian teams, 1 European teams are in the same file as Australia, Paraguay and Ecuador.

2. Eight of the nine European teams except the seed team were included in the same file; Five African teams are in the same file as 1 European teams, Paraguay and Ecuador; Four Asian teams are in the same document as three Central and North American teams outside Mexico and Australia.

3. Eight of the nine European teams except the seed team were included in the same file; Five African teams are in the same file as Australia, Paraguay and Ecuador; Four Asian teams are on the same level as three Central and North American teams outside Mexico and the European team of 1.

Considering that the teams in the same file should be as close as possible, and the European teams listed separately may be relatively strong, the second of the above three schemes is most likely to be used in practice. On the other hand, one of the three seed teams of Brazil, Argentina and Mexico is bound to be surrounded by two European teams in the group stage, which may not be a good signal in the past. Argentina had a similar painful experience in the World Cup in Korea and Japan.
