FIFA on Tuesday confirmed the pots for Friday's World Cup draw, putting the seeded teams in Pot 1, the African and South American teams in Pot 2, the CONCACAF and Asian teams in Pot 3 and the remaining nine European teams in Pot 4.
To make the number in each pot equal, at the start of the draw, one of the nine European teams will be drawn into Pot 2, and will definitely face one of the seeded South American sides.
Eight teams were seeded with host Brazil and the top seven in FIFA’s October rankings.
The other 24 teams were placed in pots based on "geographic and sports criteria."
At Friday’s draw, one team from each pot will be placed in each of the eight World Cup groups.
The draw will be organised so that there will be no more than two European teams in any group of four countries, and all the South American teams will be kept apart.
