Germany and Slovakia meet in Leipzig on Monday in a straight battle for first place in Group A, with the fixture carrying the difference between automatic World Cup qualification and the play-offs.
Both teams arrive level on points and assured of a top-two finish, but only the group winner will progress directly to the 2026 tournament.
Germany have a narrow advantage due to their superior goal difference, which means a draw would be enough for them.
They cannot afford to lean too heavily on that margin, because a defeat would push them into the play-off route and undo the momentum they have built since losing to Slovakia in their opening qualifier.
They strengthened their position last week with a 2-0 win away to Luxembourg, where Nick Woltemade scored twice to continue a strong start to his international career.
The result kept Germany top on 12 points and extended a four-match winning run that has steadied their campaign after early pressure.
Monday presents an opportunity to demonstrate that they are capable of managing a high-stakes contest against an opponent who has already beaten them in this qualification campaign.
Slovakia arrive with confidence and with a full understanding of what is required to reach the World Cup for the first time since 2010.
They kept pace with Germany by beating Northern Ireland 1-0 thanks to a late Tomas Bobcek goal and continue to show the durability that has marked much of their qualifying run.
Their record in the group includes four wins from five, and their defensive structure has been one of the most consistent elements across their campaign.
Their recent history against Germany also gives them encouragement. Slovakia have won two of the last three meetings and have often caused problems with their direct play and organisation.
They know they must win to top the group, but they also know they are capable of unsettling Germany in moments where pressure tightens.
The margins for qualification could not be clearer, and the contest is likely to demand composure, discipline and a willingness to play without fear from both sides.
