Northern Ireland (FIFA Ranking 44) have been placed in Group B2 with Switzerland (ranked 24), Turkey (ranked 58) and Malta (ranked 88) ... ... [while qualifying] for the World Cup, which will be held in Brazil, follows the same format as the Nations League and is split into three tiers.
Only the four group winners in League A will automatically qualify for the finals, with the remaining teams having to go through the play-offs for the remaining eight places.
The qualifiers will be played across six matchdays, on a home and away basis, during 2026, starting on 3 March and finishing on 9 June.
Uefa has been allocated 11 places for the 32-team 2027 World Cup.
An additional European team could also qualify through Fifa's intercontinental play-offs.
What is the play-off route for League B?If Wales, Scotland and Northern Ireland are to earn a play-off they must avoid finishing bottom of their respective groups.
Not only would they be relegated to League C they would also miss out on a play-off.
On the other hand, if they were to win their respective groups, they would not only earn promotion to League A but their first-round play-off would be against a side who finished second or third in League B.
Likewise, if Scotland, Wales or NI were to finish second or third in their group they would face a side who finished in fourth place in League A or a League B group winner.
The second round of the play-offs are seeded, and if they progress they would likely face League A opposition.
So, in short, if Wales, Scotland or NI are to reach the World Cup they will likely have to defeat two strong nations along the way.
