The Derby of the Eternal Enemies (Greek: Ντέρμπι των αιωνίων αντιπάλων), also known among fans as the Mother of All Battles (Greek: μητέρα όλων των μαχών), is an association football derby contested between two of the most successful clubs of Greece, Olympiacos from Piraeus and Panathinaikos from Athens, the two main cities in the major Athens urban area. The derby is traditionally included among the world's top 10 greatest football derbies by the international media, along with rivalries such as Real Madrid–Barcelona, Liverpool–Manchester United and Boca Juniors–River Plate. American network CNN has ranked the Olympiacos–Panathinaikos derby among the ten greatest football rivalries of all-time. In October 2014, BBC named the Olympiacos–Panathinaikos derby as "Europe's maddest derby" and in September 2019, Daily Mirror ranked the derby of the eternal enemies as the fifth most important derby in the world.
