is widely known in Greece as the "Palotai massacre" with Olympiacos coming close to one of the biggest comebacks in European Cup history. Domination in the early 1980s, UEFA Cup quarter-finalists (1975–1996) Following Goulandris resignation from the presidency in 1975, the team went through a relative dry spell in the second half of the 1970s. However, in the summer of 1979, the Greek championship turned professional and Stavros Daifas became owner and president of the club. Olympiacos emerged again as the dominant force in Greek football, winning the title four times in a row (1980, 1981, 1982, 1983) with players like the relentless goalscorer Nikos Anastopoulos, Martin Novoselac, Vicente Estavillo, Thomas Ahlström, Roger Albertsen, Maik Galakos, Tasos Mitropoulos, Takis Nikoloudis, Nikos Sarganis, Nikos Vamvakoulas, Giorgos Kokolakis, Vangelis Kousoulakis, Petros Michos, Takis Lemonis, Christos Arvanitis, Petros Xanthopoulos, Stavros Papadopoulos, Meletis Persias, Giorgos Togias and Kostas Orfanos. Kazimierz Górski, the iconic Polish coach, led Olympiacos to the 1980, 1981 and 1983 titles (winning also the Double in 1981, the 9th Double in Olympiacos' history) while Alketas Panagoulias, who had also been manager of the Greece national football team and the United States national team as well, led the team to the 1982 title after a memorable 2–1 win (Estavillo 6', Anastopoulos 69') against arch-rivals Panathinaikos in the crucial Championship final match in Volos. With Panagoulias as head coach, Olympiacos won the 1986–87 title as well, having a solid roster with players from the early 1980s like Anastopoulos, Mitropoulos, Michos, Xanthopoulos and other strong players like Miloš Šestić, Giorgos Vaitsis, Jorge Barrios, Andreas Bonovas, Alexis Alexiou and Vasilis Papachristou. Olympiacos experienced its darkest days from the late-1980s until the mid-'90s. In the mid-'80s, Olympiacos came into the hands of Greek businessman George Koskotas who was soon accused of and convicted for embezzlement, leaving Olympiacos deep in debt. The club went through a period of administrative turbulence until 1993, when Sokratis Kokkalis became majority shareholder and president of the club. As soon as he took the club's presidency, Kokkalis agreed a settlement to pay off all the club's debts and started reorganising and restructuring the club. On the pitch, the team, with all the financial and managerial problems, as well as the lack of strong administrative leadership until the Kokkalis arrival, spent nine seasons without a league title, from 1988 to 1996, despite the foreign top-class players that played for the club at that
