Germany has the deepest squad in the tournament, but it faces several questions regarding injuries. Coach Joachim Low said goalkeeper Manuel Neuer, who has not played a competitive match since fracturing a foot in September, will be his starter in Russia. That will send Marc-Andre ter Stegen, who played well at Barcelona this season, back to the bench. But can Neuer stand up to the World Cup grind? Midfielder Mesut Ozil, meanwhile, is in a race to heal his knee before next weekend’s opener with Mexico. Another worry: Germany, which went 10-0 with a plus-39 goal differential in World Cup qualifying, was winless in its next five.
