The same year around autumn, the new club split in two different squads: One team, led by the Andrianopoulos brothers and goalkeeper Kostas Klidouchakis, formed Olympiacos Omilos, which evolved into
Olympiacos; the other, led by Kostas Ferlemis, Christos Peppas and Giorgos Chatziandreou merged, with an independent club named "Young Boys" to form Peiraikos Omilos, which in turn evolved into
Ethnikos Piraeus. Following a series of mergers between other
Piraeus and
Athens based clubs, as well as an Athens football Championship, Andrianopoulos and his brothers went on to create
Olympiacos in March 1925. Giannis, Georgios, Konstantinos and Vasilios, Leonidas went on to make the newly formed
Piraeus Club famous throughout Greece. Two other brothers, Aristides and Stelios Andrianopoulos, were playing in other Piraeus football clubs. Giannis Andrianopoulos was the oldest of seven brothers who, like him, would go on to become famous footballers in the Olympiacos' ranks. As a result, Yiannis and his brothers earned Olympiacos the name
Thrylos meaning "Legend" in Greek, a nickname which the club carries to this day. Giannis was certainly the brother who made the biggest impact towards the club, even becoming a player-coach; Olympiacos' first coach, from 1925 until 1927. In 1929, he retired from football, and became Olympiacos' president for 3 years. ==International==
