There was a heavy rain before the match and an area of the stands at Westfalenstadion (Dortmund, Germany) leaked, creating waterfalls pouring from the roof down to the seats.
In addition to the waterfall incident, fans of the two teams also fought in Westfalenstadion before the match.
Even though there were barriers on both sides of the stands, Turkish and Georgian fans still managed to fight. Security had to work hard to stabilize the situation.
