The BVB boss believes that acts of violence from supporters are not an issue of the game itself, and he is satisfied with his side's development during the campaign so far
According to German police statistics, acts of violence by fans in the country have raised by 120 per cent during the last 12 years, but the CEO disagrees with part of the public who are prompting clubs to solely take responsibility for the incidents.
"The issue is not within football itself," the 53-year-old told Sky Sport News, adding: "It is a society problem. There are more injuries [occurring due to riots] at Oktoberfest."
"Pyrotechnics are an absolute no-go, because they are simply too dangerous. That is a fact. We are constantly in controversial and constructive discussions with our fans. We try to convince our fans."
He then took the time to reflect on Dortmund's development in the league and commented on the Bundesliga title holders' goals for the season.
"We are satisfied with the draw [against Bayern Munich], because we showed that we can keep up with them," he explained.
"However, we should not just talk about Dortmund and Munich. Bayern lost two points of their lead over Bayer Leverkusen. The league is not completely lacking tension."
