Mats Hummels' late header sealed Germany a 2-1 win over the Czech Republic in Prague to leave the defending champions on the brink of qualifying for the 2018 World Cup.
Timo Werner latched on to Mesut Ozil's fine pass to give Group C leaders Germany a fourth-minute lead, but Vladimir Darida levelled for the hosts with a 25-yard effort 12 minutes from time. But the Germans secured the three points when Kroos floated a free-kick to Hummels, whose bullet header flew past Vaclik.
Mats Hummels headed home an 88th-minute victor from Toni Kroos' free-kick to maintain Germany's 100% record and five-point advantage over Northern Ireland.
The Czech Republic has only suffered one defeat and now has nine points good for third place in Group C. However, that lone loss was a 3-0 defeat against Germany away from home which does indicate that this could be another tough game. Their last throw of the dice will be on Monday when they visit the Irish. Group winners from the nine groups qualify automatically for the 32-team World Cup in Russian Federation, while the eight runners-up go on to play-offs to decide the other four tournament places allocated to Europe.
Five takeaways from Western Michigan's Week 1 loss to USC
USC LB Cameron Smith missed the first half, serving a one-half suspension due to a targeting penalty in January's Rose Bowl. USC's offense displayed no ills early, at least not on its first drive, reaching the end zone two minutes into the game.
'As a team we want to stand for good values and a tolerant, open-minded Germany. "In our build up play, we often served the ball up to the Czechs and made life hard for ourselves". Michael Krmencik fired over after trying to lob Barcelona goalkeeper Marc-Andre ter Stegen in the German goal.
Borussia Monchengladbach forward Lars Stindl was Werner's attacking partner and he nearly added a second after 19 minutes only to see his low shot blocked by Vaclik's legs.
Taking a touch to set himself, Darida cut across the ball with a stunning long-range effort that left Ter Stegen grasping at thin air as he helplessly dived high to his left.
Norway beat Azerbaijan 2-0, but both sides are effectively eliminated, sitting nine points behind NI and with much worse goal differences.
San Marino are bottom after losing all their games.
