They benefit from the fact that they have 3 of their final 4 games at home, one of which includes a second meeting with Montenegro. It also helps that they have a huge lead in damn right now. However, they certainly have reason to be fearful if they don't manage to end up winning the group. Apparently there has been no mention yet of seeding the draw for the play-ins, and if it isn't seeded then the possibility is out there that they could draw France and then one of those two would miss the WC altogether.
