Timo Werner and Anthony Rudiger were on the scoresheet as Germany moved four points clear at the top of Group J thanks to this convincing victory over Iceland, with additional goals by Serge Gnabry and Leroy Sane.
Wener’s goal was a neat effort after his shot crashed off the post but spun over the line.
If the win against Liechtenstein was the slow start and the hammering of Armenia the arrival of Flick’s Germany then the win in Iceland was the professional performance that Germany has not always delivered.
There were no nervy moments in this one.
In front of a largely loud and proud set of 4,000 home fans in the rustic Laugardalsvöllur stadium in Reykjavik, Germany looked in control throughout, not suffering from what became a habitual crisis of confidence under Joachim Löw.
If there was a criticism, it was that they didn’t score as much as their play deserved, although Flick will be happy that Timo Werner did eventually get a goal.
Deservedly it was Leroy Sané, who again looked strong down the left, who scored the decisive third. For all the talk of the lack of a striker being an issue, Serge Gnabry was also on the scoresheet again, taking his international tally to 19 goals in 29 games.
There was even a set-piece goal, Antonio Rüdiger’s header a nice hat tip to new set-piece coach, Dane Mads Buttgereit, albeit two games after some underwhelming corners.
