The Rundsporthalle was opened by the former Leverkusen mayor Wilhelm Dopatka, Dieter Kürten was the host at the opening event that included mini-football, music and dance. The singer Bata Illic, the duo Nina & Mike plus the Bayer 04 Veterans team led by goalkeeping legend Fredy Mutz provided an entertaining evening. Berti Vogts, Wolfgang Kleff and Wolfgang Fahrian were there along with Manfred Ommer, the Olympic medal winners Rita Wilden and Harald Norpoth and Olympic championr Willi Holdorf. A USA basketball team from the German Bundesliga played for ten minutes against the TuS 04 basketball side.





Just one month later, several of the downlighters at the Rundsporthalle fail during the first competitive match for the women's basketball side. The technicians are unable to effect a repair during an eight-minute break. Despite the reduced lighting, the match is concluded.
Up to February 2009, the sports hall was officially named the Wilhelm-Dopatka-Halle after the longstanding Leverkusen mayor. It was later renamed the Smidt Arena after a new sponsor. Since the takeover of the furniture store by the Ostermann company, the hall has been called the Ostermann Arena since October 2016.

Minas Hantzidis was born on 4 July 1966 in Kettwig, near Essen, and he grew up in Germany. He developed a passion for football at a young age and, whilst still a youth player, moved from Wuppertaler SV to Bayer 04. The attacking and goal-scoring midfielder then made a name for himself in his first senior season at Bayer 04. In the reserve team, he scored goal after goal in the first half of the season, soon began training with the first team and was brought on as a substitute for the first time by manager Erich Ribbeck on 22 November 1985 in a home match against Bayern Munich.

Sascha was born on 3 July 1986 in Leverkusen. He is the son of former Bundesliga 2 player Manfred Dum, who mainly scored goals for Union Solingen but also played for FC Saarbrücken, SC Freiburg and Wuppertaler SV. Sascha started playing for the youth teams at HSV Langenfeld at an early age. There, he caught the eye of scouts from Bayer 04 and joined the club at a young age. Following a growth spurt in the U15 team, which forced him to take a nine-month break, the left-footed player finally had the ideal conditions to establish himself in the Bayer 04 youth ranks. Even as an U17 player, he made the leap into the U19 team. Blessed with immense pace, Sascha primarily played in attacking midfield. Not the most technically gifted, but possessing a powerful shot, he found himself training with the first team in the summer of 2005 alongside Gonzalo Castro, while he was still a U19 player.

The Werkself could not have hoped for a better start to the Bundesliga 2 North season in 1976/77. At the end of a week-long training camp in Quickborn, Schleswig-Holstein, coach Willibert Kremer’s side secured two convincing victories over BSC Brunsbüttel (5–0) and TuS Holstein Quickborn (6–0). Following this flying start, Bayer 04 faced a considerably tougher challenge on 23 July 1976 at 19:30 CEST at the Ulrich Haberland Stadium against Bundesliga side Karlsruher SC.

Hans Sarpei was born on 28 June 1976 in Tema, Ghana, and came to Germany with his parents at the age of three, where he grew up in Cologne. Even before he was born, his mother and father worked in Hamburg in the import-export sector. There they met an older man who introduced them to German culture and supported them. Out of gratitude, Hans was later given his first name, although this man died before he was born. Hans comes from a sporting family; his older brother Edward and his nephews Hans Nunoo Sarpei and Kingsley Sarpei were or are also professional footballers.
