Born in
Mytilene,
Lesbos, Grammos began playing football as a winger for Achilleas Mytilene until he was acquired in 1966 by
Panathinaikos for 600,000
drachmas, at a time when the "greens" were looking for young players to replace six of the older stars that had rebelled against coach
Stjepan Bobek. Grammos played as right forward or right midfielder. He was a mainstay for Panathinaikos for the next 10 years and was a member of the team that played at
1971 European Cup Final in
Wembley Stadium. Later in his career, he played for
Olympiacos, becoming one of the few players that made the cross-over between the two "eternal enemies". Grammos made a total of 215 appearances in the
Alpha Ethniki. == Honours ==
