There are few teams in world football more universally loved than Germany's Borussia Dortmund.
Lucien Favre's side have a huge neutral following across the globe, which is mainly down to their incredible stadium and support.
The Signal Iduna Park is a footballing amphitheatre, possessing a humungous free-standing grandstand which holds around 25,000 fans - known as the Yellow Wall.
And the videos and images of the grandstand prior to kick-off show that amazingly, the Dortmund fans even surpassed their own lofty standards yesterday evening.

Just take a look at the evidence below and marvel at the greatest supporters in world football.
If for some reason, a trip to Dortmund was not on your footballing bucket list, it simply has to be now. You're even allowed to drink a nice cold beer in the stands.
The game itself was one of the best 0-0's in quite a while, with Barca lucky to leave Germany with a point despite the reintroduction of Lionel Messi as a second-half substitute.
Dortmund hero Marco Reus missed a second-half penalty, while summer signing Julian Brandt struck the crossbar late on with a thunderous long-range effort.
The two sides will meet again on match day five on November 27 in what could be a crucial game in the context of the group.
Both teams are favourites to progress, but Inter Milan and Slavia Prague - who drew 1-1 at the San Siro last night - may have something to say about that.
