We saw great photos of this on Dirty Tackle a couple days ago, but have been waiting for the video to emerge. And it is fantastic.
Fourth tier German side Magdeburg had gone five games without scoring, and their fans were geting fed up. So for a home game against Berliner AK 07, the supporters (apparently the only people in attendance) brought fluorescent arrows to point the way to the opposing goal. Very creative, and they did indeed score on a 79th minute goal from American Christopher Wright, but Magdeburg still lost 2-1. [FC-Magdeburg.de]
