The Republic of Ireland have been drawn against Denmark in the play-offs for the 2018 World Cup and Northern Ireland will face Switzerland for a spot in the finals.
Both nations avoided four-time winners Italy and will be hopeful of booking their place in Russia next summer.
Martin O'Neill's Republic beat Wales last week to seal their spot as runners-up in Group D while Northern Ireland finished second to Germany in Group C.
The two-legged ties will take place between 9-14 November, with Michael O'Neill's Northern Ireland at home in the opening leg, while the Republic of Ireland travel to Denmark.
Sky Bet make the Republic 11/10 outsiders to qualify for the World Cup from their tie with Denmark, who are odds-on favourites at 4/6 to progress.
Northern Ireland are a bigger price at 2/1 to make it through against Switzerland, who are as short as 4/11 to book their place in Russia.
