In 1990, German coach Sepp Piontek was put in charge of the national team. Under his guidance, a group of new players debuted for the national team. Many of these players (which included Bülent Korkmaz, Alpay Özalan, Sergen Yalçın, Rüştü Reçber, and Hakan Şükür) would become the backbone of the national team for many years. Piontek's mission came to an end in 1993, where he was replaced by Fatih Terim, who in turn managed to qualify for Euro 1996. Turkey qualified for its first major tournament since 1954, marking another turning point for Turkish football after having failed to qualify for both Euro 1992 and the 1994 World Cup. The appointment of Piontek was a recommended move by another German coach, Jupp Derwall, who had coached Galatasaray for three seasons. Derwall is regarded as the revolutionizer of Turkish football, since his introduction of modern Western European training techniques and tactical ideas to the Turkish game also heavily influenced the national team.
