Hummels doesn't strike me as particulary fast . I agree that boateng is fast , but he is a poor cb imo . Mertesacker and howedes are both slow , mertesacker being dreadfully slow . Except today lahm played in midfield on the start of the match , althrough i hope he continues to start as a rb .Goezte has been playing rather poorly imo , ozil hasn't played that well either , but i think he could give more as an AMF
My best german lineup
-------------neuer
lahm-hummels-????-schmelzer
------sweini-----kroos
muller------ozil--------reus
-------------klose
With reus and schmelzer on the team , a good cb with some decent speed near hummels and i think that have a team that could give much more than their current line up
