I think the commentators on the red button must have read your post.Germany seem almost capable of creating chances, but don't really have anyone to aim for. I know the closest thing to a pure target man they have is injured, but it might be time to bring on a Schurrle, Gotze or even (I feel ridiculous saying it) Podolski.
It's extremely difficult to coordinate that across an entire stadium because of the slow tempo as well as the fact that the tempo changes. You need a visual cue that everyone can see, such as someone at the bottom acting as conductor, which I assume Iceland had. A sound cue like a drum can work in small crowds such as in the Scottish video (I really hope people stop calling it the Viking chant and give those Scottish and Polish fans due credit), but it doesn't work in large crowds because sound takes time to travel.They're really making a mess of that Viking chant, they don't leave nearly enough time between 'huhs' and it just doesn't work.
Muller's incompetence this tournament has hurt them a lot. I'm surprised he's still being played every game.Germany can't score without a real striker. It's their main problem.
