Northern Ireland 2-0 Czech Republic
Northern Ireland have already sealed second place, but only the best eight of the nine runners-up qualify for the play-offs (excluding results against the bottom team in each group).
At the moment they're fine. But they could do with a result against Germany at home or Norway away to ensure they are not the worst second-placed team.
Of course, win both those games and hope Germany lose to Azerbaijan, and they will qualify for the World Cup automatically.
