backlog. BFC Dynamo is cooperating with those responsible for the Sportforum and the Berlin Football Association (BFV) to find common solutions for the most urgently needed construction work. The Senate of Berlin is planning to invest €3 million in the Sportforum as of 2020. The money is part of the budget for the demolition of the Friedrich-Ludwig-Jahn-Stadion. BFC Dynamo officially announced on 21 March 2021 that it has now returned to the Sportforum, as the operating permit for the Friedrich-Ludwig-Jahn-Stadion expired on 31 December 2020. The Sportforum was equipped with a floodlight system in April 2021. The club organized a work effort in the summer of 2021 to get the stadium in shape for the upcoming Regionalliga season. Supporters gathered and cleared sections of the old stadium from weeds. Members of the interest group IG BFC'er also restored the iconic manual scoreboard in time for the first home match of the 2021–22 season against Energie Cottbus on 28 July 2021. Future stadium The Friedrich-Ludwig-Jahn-Stadion is planned to be demolished towards the end of 2023 for a complete redevelopment. The new Fredrich-Ludwig-Jahn-Stadion is designed as an inclusive sports facility. The stadium will hold 20,000 spectators and meet the requirements for play in the 3. Liga and 2. Bundesliga. BFC Dynamo will be able to play matches at the new stadium. The new Friedrich-Ludwig-Jahn-Stadion is planned to be opened in 2028. Supporters East German era BFC Dynamo played only a minor role in football in Berlin until the relocation of FC Vorwärts Berlin to Frankfurt an der Oder in 1971. The club initially had modest support, but with its growing successes in the 1970s, the club began to attract young fans, primarily from the central areas around the Friedrich-Ludwig-Jahn-Sportpark, such as Prenzlauer Berg and Mitte. Many came from working class families in Prenzlauer Berg. One of the first big supporter groups of BFC Dynamo was Black Eagle. The fan club was founded in 1972 and was one of the earliest fan clubs in East German football. Fans of BFC Dynamo were the first to sew their embroidered fan club badges on their jackets. This was a novelty among football supporters in East Germany in the 1970s. The supporter scene became a focal point for various subcultures in the late 1970s and beginning of the 1980s. There were punks, rockers, hippies and a few early skinheads. Some were left-leaning and others were right-leaning.
