Symeon Papadopolos was born on April 18th 2000 in Thessaloniki, and began his football education from a young age in the club’s youth ranks. He moved to Iraklis before re-joining PAOK in 2017.

At Iraklis he enjoyed plenty of action in the Under-17 side, even if he was a year younger at that level. He was a member of the mixed clubs team in the MFCA championship and was called up numerous times for the Greek national youth teams.

From 2017 when he returned to PAOK, he made 22 appearances for the club in the Super League Under-20 championship. He followed that up with a great season the following year (2018-19), winning the league title with the Under-19 side and enjoyed a memorable run in the UEFA Youth League. In the summer of 2019, after taking part in pre-season training with the first team, he was elevated to third choice goalkeeper, behind Paschalakis and Zivkovic.
