Olympiacos Piraeus added more talent to its roster by signing a four-year contract with forward Vasilis Charalampopoulos, the club announced on Wednesday. Charalampopoulos (2.02 meters, 22 years old), who can play both forward positions, returns to the Turkish Airlines EuroLeague after couple seasons. He made his debut as a 16-year old with Panathinaikos Athens in December of 2013, and has made a total of 26 appearances with the Greens over four seasons, while helping the team win three Greek League and five Greek Cup trophies. Last season he played with Lavrio and averaged 7.5 points and 3.1 rebounds in 12 Greek League appearances. Charalampopoulos has also played on-loan with PAOK Thessaloniki, and has been a member of a Greek national team.
