Low's three-man attack, which lacked a recognized center forward, looked to be an inspired choice in Germany's opener against Portugal. Since the Mannschaft's four-goal haul against the Seleccao, the tactic has appeared somewhat less convincing.
Germany struggled to break down the Ghana defense in the absence of a natural striker, a Mario Gotze goal coming from precious little. And against the United States, Thomas Muller's winner only came after the Bayern man was moved to the wing with the introduction of Miroslav Klose. And it was Klose himself who netted the equalizer against Ghana.
Analyzing the merits of playing Klose statistically, Germany have scored two of their seven goals with Klose on the pitch. With Klose playing, they score every 33.0 minutes. Without him, they score every 47.4 minutes. Due to small sampling size, however, statistics are not convincing on their own.
It's relevant to note that two of Germany's goals without Klose were scored against 10 men and three with Germany already in the lead. In the veteran's presence, the Mannschaft were always either on level terms or behind.
On the other hand, Klose is 36 years of age and has certain physical limitations, especially in the heat of the Brazilian summer. Combining his minutes, he played less than a full game during the group stage and as a result was fresh when he came on.
Low has done well to closely monitor his approach with each game, separating each fixture into several distinct tactical battles. Using Klose as a "silver bullet" to close out games, especially in knockout rounds, could well remain his approach. After all, it took less than two minutes after coming on against Ghana for Klose to score.
