Top 10 European football clubs that have never been relegated

#16 Panathinaikos

Today a part of Panathinaikos A.O., they are the oldest active football club in Greece, initially founded only to practice this sport. Created in 1908 as “Podosfairikos Omilos Athinon” (Football Club of Athens) by Georgios Kalafatis, they play in the Super League Greece, being one of the most successful clubs in Greek football and one of three clubs which have never been relegated from the top division. Amongst their major titles are 20 Greek Championships, 18 Greek Cups, achieving eight times the Double, and 4 Greek Super Cups. They are also the only club that won a championship undefeated, going without a loss in a top-flight campaign (1963-64 season), a feat that no other club in Greece has ever been able to achieve.
