In terms of being an innovative up-tempo side, Germany have gone backwards since 2010 when they were by far the most enjoyable side to watch in the competition.
They are a lot more methodical now and as a result are a better team. But they have struggled against the two high tempo teams who played in a fearless manner- Algeria and Ghana.
So long as Brazil play the style they've been playing for the most part of the tournament, they'll win.
If they sit too much and don't break in enough numbers, Germany will eventually win.
