Scotland, Wales and Northern Ireland begin on the road to Qatar 2022 later this month, the home nations aiming for a place on the world stage next winter.
On a high from qualifying for this summer's European Championships, Scotland have been drawn alongside Denmark, Austria, Israel, Moldova and the Faroe Islands.
With Steve Clarke having fashioned a side that is difficult to break down, they will fancy their chances of at least earning a play-off by finishing in the top two in their group although a lack of firepower is a problem that needs addressing.
Also qualified for the Euros, and with excitement growing about a young, improving side, Wales continue their quest for a first World Cup appearance since 1958.
They open qualifying with a tough test away to Belgium in a group that also contains Estonia, Czech Republic and Belarus.
Northern Ireland just missed out on a place in this summer's tournament and are now preparing to face Italy, Switzerland, Bulgaria and Lithuania in Group C.
