After the German reunification in 1990, Reiner Calmund was quick to sign East German stars Ulf Kirsten, Andreas Thom and Jens Melzig. The three players would become instant crowd favourites, and make significant contributions to the team. Calmund also established groundbreaking contacts in Brazilian football, befriending Juan Figer, one of Brazil's most powerful player agents. Over the next few years, budding superstars, such as Jorginho and Paulo Sérgio, joined the team, as did Czech star Pavel Hapal. The club also signed charismatic players, such as Bernd Schuster, and Rudi Völler, helping to ensure the team's popularity and growing success.
