Dortmund fans gathered nine hours before Mainz clash!

Borussia Dortmund could end Bayern Munich's dominance after decades. Edin Terzic's side have not won a Bundesliga title for 11 years but could add another title to their trophy case on Saturday.
Dortmund are in first place with a two-point lead over Bayern. They could lift the Bundesliga trophy if they win on Saturday against Mainz 05 at Signal Iduna Park.
The fans are very excited because they see the title getting closer and closer and have been supporting their team since Saturday morning.
The German club posted on Twitter that fans were on the streets supporting Dortmund nine hours before kick-off.
