The first team is based on the top 7 ranked by FIFA before the draw (+the host is 8 teams).
The second team is all European except the seed team (mainly considering geographical avoidance)
The third team is five African teams except the host South Africa. All South American teams will be divided into three teams: Asian teams, North American and Caribbean teams and teams entering the play-offs (such as Portugal). Because a country can't be at its peak for a long time, or at least play games, some champions don't rank high before the draw.
Not a first-class team, but a second-class team. At this time, there will be a champion team or a strong team plus a first-class team in the group (the strength of the first-class team is not bad), and the competition in Europe is very strong. Many European teams have to play play-offs to reach the top 32, and teams playing play-offs will be assigned to the fourth-level teams. At this time, a team should have a weaker level 4 team besides the first and second level teams. As a result, the unlucky European team in the qualifiers came and that group appeared. A seed team, two European teams, a third team and the death group appeared. Although it is very complicated, the probability of the death group is actually very high, not 65,438+000%, but 99%, because no team can always be brilliant.
