Derby of the eternal enemies

The derby of the eternal rivals (Greek: Ντέρμπι των αιωνίων αντιπάλων), also called mother of all battles (Greek: μητέρα όλων των μαχών), is a football local derby in the metropolitan area Athens- Piraeus between the most successful clubs of Greece, Olympiacos and Panathinaikos. The rivalry between the clubs and their fans is intense, thus this derby has always been a classic for the Greek capital, as well as the whole of Greece, the most prestigious in the country. 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.
