Injuries have depleted Germany's defense in such a way that its opening match against Portugal may see four central defenders in the starting line-up, with two of them out of position and two who have rarely played together.

Coach Joachim Loew didn't seem unduly worried on Friday about the prospect, confirming that his back four may feature four central defenders.

Captain and right back Philipp Lahm could move into the midfield, with Jerome Boateng taking his place in Monday's Group G match. The left back position could go to Benedikt Hoewedes, while Mats Hummels and Per Mertesacker would be the central defenders.

Loew explained that fullbacks would not play as big a role at the World Cup as in qualifying, when teams usually play very defensively against Germany.
