The 32 teams are arranged in four pots ("
Bombo", in spanish), eight teams in each. The distribution of the countries is defined according to the FIFA ranking, used to assign the classified teams in each of the four pots.
The eight drums that represent the groups are labeled with letters from A to H.
These were the countries classified when the draw was made in April (3 were yet to be defined).
In each of them, there will be four balls with the numbers of the positions of the selections (1, 2, 3 and 4) in the respective group.
First, a ball will be drawn from the selection pot and immediately another from one of the group pots, in this way, the positions in which the different teams will play will be assigned.
The first seven are accommodated in Pot 1 along with the host (Qatar) who will be seeded from Group A and so on consecutively with the other pots.
FIFA will ensure, to the extent possible, that no group has more than one team from the same confederation, with the sole exception of Europe, which is represented at the World Cup by thirteen teams. Each group will have at least one and a maximum of two two European teams. In this way, five of the eight groups will include two European teams.
