for the
Inter-Allied Games in
Paris, 1919. Kalafatis is seated, second from right. Being a big athletic talent, he distinguished himself in track and field sports. But
football was his big passion. He played for
Ethnikos G.S. Athens and when his later club
Panellinios decided to discontinue its football team, Kalafatis together with 40 other athletes broke away and established in February 1908 the first team of
Panathinaikos, named Podosfairikos Omilos Athinon (
Football Club of Athens). Kalafatis appointed the Englishman
John Cyril Campbell as coach for the new team. It was the first time that a foreigner was appointed as the coach of a Greek team. Apart from Giorgos Kalafatis, other establishing members of POA were: his brother
Alexandros, who was the first president, Emmanouel Chrysis, Dimitris Doukakis, Periklis Mpoumpoulis, Vasileios Granitsas, Mantzakos, Papageorgiou, Gaetas, Demertzis, Stavropoulos, Paschos, Misakian, Reppas, Sapounias and Garoufalias. In 1919, he was a member of the
Greece national team for the
Inter-Allied Games in
Paris. In Paris, Kalafatis collected information about
basketball and
volleyball (sports unknown then in Greece) and after his return to Athens, started his efforts on creating new teams with
Panathinaikos. He was a player/manager in the
Greece national team for the
1920 Olympic Games in
Antwerp. His older brother, Alexandros, was selected for the unofficial Greece national team that played in the
1906 Summer Olympics in
Athens, starting in both games which ended in 1–5 and 0–9 losses. Kalafatis played football until the early 1920s. After he retired, he remained in Panathinaikos as an official. ==Personal life==
