Brondby has been at the center of a major scandal involving former coach Thomas Frank. In 2013, Frank was appointed head coach of Brondby, where he was tasked with lifting the club out of a difficult period. Under his leadership, Brondby improved significantly and moved closer to the top of Danish football. However, in his third year as coach, a controversy arose that shook the entire club. An anonymous user on a supporters' forum, calling themselves 'Oscar', criticized Frank and the then-sporting director Per Rud. It later turned out that 'Oscar' was the club's own chairman, Jan Bech Andersen. This revelation led to Thomas Frank resigning as coach. The incident has been described as one of the biggest scandals in Danish football history. Frank left Brondby and later found success in the Premier League with Brentford, where he has showcased his coaching talent. The scandal has had significant consequences for Brondby, creating upheaval in the club's management and impacting its future.
