Clarifying tournament rules
Bracket structure ensures that winners from specific groups are in the same half of the draw. Argentina and Spain could potentially meet before the final based on their group placements. The idea that they "won't meet before the final" isn't accurate, especially with past instances in mind. Since both teams are from different confederations, they could actually be drawn into the same group and face each other in the group stage. That's definitely a possibility!Explaining World Cup draw rules
It’s true that UEFA allows up to two teams per group in the men's World Cup, making the earlier claim incorrect. Argentina and Spain, being from different confederations, could actually be placed in the same group, allowing them to meet during the group stage. Additionally, they could face each other in knockout rounds, like the Round of 16 or Quarterfinals. I should clarify about the formats for recent World Cups, noting the shift from 32 teams to 48 in 2026!Clarifying tournament format
The 2026 World Cup format updates indicate there will be 12 groups of 4 teams. The top two from each group, plus eight of the best third-placed teams, will advance to a 32-team knockout stage. The bracket isn't entirely predetermined; it hinges on the complexity of mapping third-placed teams. Importantly, Spain and Argentina could still face each other before the final, even in the same group, since UEFA allows two teams per group. The only constraint is that other confederations can’t have more than one team in a group.Exploring tournament seeding rules
Yes, Spain and Argentina can indeed be drawn together since they belong to different confederations. Regarding seeds, Pot 1 teams can't be in the same group, which means if both teams are in Pot 1, they can’t be grouped together. They could, however, meet in earlier knockout rounds like the Round of 16, depending on how the groups play out—such as one finishing second. If both win their groups and are on opposite halves of the bracket, they'd only meet in the semifinals.Clarifying knockout round possibilities
Here’s a concise correction regarding whether Spain and Argentina can meet before the final:
- Conclusion: The claim that they "won't meet before the final" isn't accurate.
- Draw Constraints: Teams from the same confederation can't be in the same group (except UEFA can have two); Argentina and Spain can be grouped together. 
- Knockout Stages: They could meet in the Round of 16 or Quarterfinals if one finishes second or they're in the same half.
- Only if a specific draw places them in opposite halves while both topping their groups would they only meet in the final.
- Which World Cup are you referencing?
不对。世界杯抽签并没有规定阿根廷和西班牙只能在决赛相遇。
- 小组赛：除同洲限制外（欧足联可同组最多两队），阿根廷(南美)和西班牙(欧洲)可以被分到同一小组，直接相遇。
- 淘汰赛：即便不在同组，只要有一方以小组第二出线，或两队被分在同一半区，也可能在1/8、1/4或半决赛碰面。 
- 只有在某一届的具体签位把他们分在不同半区，且两队都按特定名次出线并一路晋级时，才会“只可能在决赛相遇”——这不是规则保证，而是当届签位与赛果共同导致的。
你指的是哪一届（男子/女子、年份）？我可以按那一届的具体签位给你画出路径。
