This is the new Panathinaikos 12/13 home football shirt shirt made by adidas.
The colours that were first used by the club in 1908 were red and white. Later changed to green and white. In 1918, player and later General Secretary of the Club, Michalis Papazoglou proposed that the club adopt the shamrock as its emblem. He used to have it sewn on his shirt since he was competing for a club in his native Chalcedon, Constantinople.
Papazoglou was possibly inspired by William Sherring, an Irish Canadian athlete who had won the Athens 1906 Olympic Marathon wearing a white shirt with a big green shamrock on it.
