After only managing a 0-0 draw in the first leg of their Champions League quarterfinal at Malaga, Borussia Dortmund fans apparently decided that something needed to be done to help intimidate the visiting underdogs on the return leg. So they did up a massive tifo display featuring an unnerving character looking through binoculars above the words "Auf den Spuren des verlorenen Henkelpotts" (On the path of the lost CL-Cup).
The BVB creeper has presumably been on his hunt since the club won their one and only Champions League title in 1997, but by the looks of him, he might have peeped through a few bedroom windows along the way. Still, this is a fantastic tifo.
UPDATE: Here's the rise of the tifo in gif form, which is even more fantastic.
