Wales, Portugal, North Macedonia, Poland and Sweden have made it to the World Cup play-off finals, with Scotland still to play Ukraine, but what happens now?
Twelve teams advanced to the play-offs in total, but how they got there was a little complicated.
Ten group runners-up from qualifying were joined by two teams who qualified via the UEFA Nations League overall ranking.
They are the two best group winners from the Nations League who have not advanced via traditional World Cup qualifying - that is as either group winners or group runners-up.
In the play-off draw, 12 teams are drawn into three play-off paths for one-legged semi-finals and finals.
The three winners reach the 2022 World Cup in Qatar.
