The 2020 Greek Cup final was the 76th final of the Greek Cup. It took place on 12 September 2020 at Panthessaliko Stadium, between AEK Athens and Olympiacos.^[1] It was AEK Athens' twenty fifth Greek Cup final and fifth consecutive, of their 96-year history and Olympiacos' fortieth Greek Cup final in their 93 years of existence. The final was originally scheduled for 26 July and was postponed to 30 August because of Olympiacos' pressure in HFF to change the stadium from Georgios Kamaras Stadium to Olympic Stadium and after the refusal of the Hellenic Police in the first stadium.^[2] The final was rescheduled for 30 August in the Olympic Stadium but it was postponed again because 2 days before the game Olympiacos' player, Maximiliano Lovera was tested positive for COVID-19.^[3] The final was rescheduled again for 12 September at Panthessaliko Stadium. Due to the delay of the match, the teams had to compete without the players acquired from the 2020 summer transfer period, by decision of the UEFA.^[4]
