What does the World Cup "seed team" mean? How to determine?

Seed team: in the competition, the stronger athletes who are arranged in each group are called seeds or seed players when they are eliminated by groups; Similarly, when participating in the competition as a team, the stronger team in each group is called the seed team.

The Organizing Committee of the 2006 World Cup in Germany held a press conference in Leipzig, Germany, and announced the lottery results of eight seed teams and other teams, and officially announced the process of the lottery ceremony on February 9, 65438. DPA disclosed in advance the eight teams that eventually became seeds, namely: Germany, Brazil, Argentina, France, Spain, Mexico, Italy and England. European giants such as the Netherlands and the Czech Republic have not been qualified for seeds, and they are facing the fate of group matches and giants. The rules for determining the seed team in previous World Cups are based on the results of the past three World Cups and the international ranking of FIFA, and the final seed team ownership is generated through certain scoring rules. Because the Dutch team failed to enter the finals of the 2002 World Cup in Korea and Japan, it fell behind the eight seeded teams in this rule. In addition, the Czech Republic, Portugal and other international ranking teams failed to qualify for the seed because of their embarrassing achievements in the World Cup in recent years.
