The 16 teams entering the draw will be split into four pots.
The 12 group runners-up will enter the top three pots in order of their Fifa ranking, with the four Nations League group winners placed into pot four.
One team from each pot will be drawn into four separate paths: Path A, Path B, Path C and Path D.
In each path, the pot one team will face the pot four team in a one-legged semi-final. The teams in pot two and pot three from each path will face each other in the other semi-final.
Teams in pot one and pot two will both be at home in the semi-finals. The draw will determine who hosts the final in each path.
So for example, the Path A semi-final winners will play each other in the final with the victor qualifying for the World Cup.
