Who can still qualify for the World Cup?
Wales are aiming to make it to back-to-back men's World Cups for the first time, but Bosnia-Herzegovina stand in their way. Craig Bellamy's side host the semi-final in Cardiff with the winners hosting the final five days later. Northern Ireland, who are aiming to end a 40-year World Cup wait, have the tough task of facing an Italy team looking to qualify for their first World Cup since 2014.
The winners of this play-off path will secure their place in Group B alongside co-hosts Canada, Switzerland and Qatar. Ukraine came second in their qualifying group behind 2022 World Cup runners-up France and lose their home advantage against Sweden due to the ongoing conflict with Russia. The semi-final will instead take place in Valencia, Spain.
Sweden finished bottom of their qualifying group, failing to win a match, but have a lifeline thanks to their Nations League performance. Poland have qualified for the last two men's World Cups and face an Albania side aiming to reach the finals for the first time. The winner of this path will be placed in Group F alongside Netherlands, Japan and Tunisia.
Turkey finished three points behind Spain in their World Cup group and now have to face a Romania side aiming to reach their first World Cup since 1998. Slovakia have also not featured at a World Cup since 2010 and must beat Kosovo - a nation aiming to qualify for their first major tournament - to progress. The winner of this play-off path will be placed in Group D alongside co-hosts United States, Paraguay and Australia.
Final: Denmark/North Macedonia v Czech Republic/Republic of Ireland Denmark missed out on automatically reaching the World Cup after a dramatic 4-2 defeat against Scotland in Glasgow. The Danes had to settle for the play-offs and now have to face a North Macedonia side aiming to qualify for a first World Cup. Troy Parrott's last-gasp winner in Hungary secured an unlikely play-off for the Republic of Ireland.
