Players don’t get assigned to World Cup teams at random — they represent a national team based on FIFA eligibility rules, and each country’s coach then chooses the final squad from eligible players.

How eligibility works

A player can usually play for a country if they:

  • Were born there.
  • Have a parent or grandparent from there.
  • Have lived there long enough to qualify under FIFA rules.

How the final squad is chosen

Once a player is eligible for a country, the national team manager picks the roster for the tournament. That means not every eligible player makes the World Cup squad; it depends on form, injuries, tactics, and position needs.

Group stage note

After the teams are selected and qualified, FIFA then places the national teams into groups through a draw system that uses rankings, pots, and confederation rules. That affects who plays who , not which country a player represents.

In short, the country is determined by eligibility, and the specific World Cup squad is determined by the team’s coach.
