Loew's bold move to play a 4-3-3 against Portugal paid off for a number of reasons, but none more so than the way it accommodated players such as Mesut Ozil and Mario Goetze in the system, while also keeping a rigid midfield to defend the back line.
One of Germany's greatest apprehensions going into the tournament was how to tweak a 4-2-3-1 formation that didn't seem to get the best out of Ozil as the No. 10 or Goetze as a false nine. Yet with this simple change to a front three, both were able to comfortably play behind Thomas Mueller to full effect.
However, Loew will be scratching his head at the prospect of returning Bastian Schweinsteiger to the side following his absence from the opening game.
Against Portugal, Germany played with a midfield trio of Philipp Lahm, Sami Khedira and Toni Kroos, who worked in perfect synchronisation as defensive midfielder, box-to-box midfielder and advanced playmaker respectively.
Who Schweinsteiger replaces in this system is hard to tell. The most obvious would be Khedira—as Schweinsteiger tends to play a similar role to the Real Madrid star and shares a natural chemistry with the other two Bayern Munich players—but a straight swap for playmaker Kroos is also not beyond the realms of possibility.
Another option could be defensive midfielder Lahm, if asked to return to defense as a result of the aforementioned injury to Hummels. Here Germany's vice-captain could quite easily sit in front of the back four, while allowing Kroos and Khedira to roam forward in search of goals and support.
Whether Loew should change things at all is still up for debate, but if he does there will be plenty of positions and roles that the Bayern midfielder can happily fill.
