In recent years, two of the most important questions concerning the German national team have been who will replace Miroslav Klose following the striker's retirement and how Joachim Low will accommodate an ever-increasing number of world-class attacking midfielders in his squad.
The answer to both, it seems, is to use Mario Gotze as a false striker.
Germany constantly looked dangerous on Friday, and critically, were unpredictable in attack. Although he lacked the physical presence of a player like Mario Gomez, the Dortmund man used different athletic advantages, namely his quickness and agility.
Rather than leaping for headers or holding off markers, Gotze made sharp turns and explosive runs and drew defenders away from central areas. More than that, his aggression and alertness to the ball made him a nightmare for the Kazakh defenders—he'd pounce on any botched clearance or deflected ball and then drive toward goal.
A case-in-point was Gotze's goal, which he took when most players from both teams were trying to understand why a foul hadn't been called against Thomas Muller.
Critically, there was synergy between Gotze and the rest of the German attack—particularly Mesut Ozil. When Gomez plays for Germany, he's typically an isolated figure up front, disconnected from the play behind him.
Kazakhstan are not exactly renowned as top opposition, and the use of Gotze in a central striker role is still yet to be justified against opponents on the level of those that will compete at the World Cup.
Still, the action on Friday was a step in the right direction. And with the return of Marco Reus to the team next Tuesday, we'll have an even better look at what Germany are capable of doing with a fluid front four.
