Some of the comments here are predicting Italy to win the game.

However I believe the following will be the deciding factors in the Germany vs Italy game:

1) Italy will face difficulties with Germany's ability to get the ball into the corner and create cross passes finished with headers

2) Fitness level, as the Italians will inevitably play defense-first strategy and the game goes longer the Italians will start to think about Germany's shootout record and Italy's shootout record. The Italians are 2nd worst only to the English in shootout records. The Italians will need to open the game up at some point but face Germany's faster speed up the flanks.

3) Home crowd advantage
