Ilias Chatzitheodoridis (; born 5 November 1997) is a Greek professional footballer who plays as a left-back for Super League club OFI.
Chatzitheodoridis is a product of the Arsenal academy and played senior football in England for Brentford and Cheltenham Town, before returning to Greece to join Panathinaikos in 2018. He transferred to Panetolikos in 2022.
A left back, Chatzitheodoridis began his career in his native Greece, playing for Mas Kallitheakos and training part-time with Arsenal's Greek academy. After impressing on trial, he signed a two-year scholarship deal with the Premier League club's principle academy in England on 6 June 2014. Chatzitheodoridis made 44 appearances and scored one goal for the U18 team over the course of two seasons, before being released in June 2016.
Chatzitheodoridis joined the B team at Championship club Brentford on trial during 2016âÂÂ17 pre-season and he impressed enough to sign a one-year professional contract on 6 August 2016. An injury crisis at left back saw Chatzitheodoridis win his maiden first team call up for a league match versus Wolverhampton Wanderers on 24 September 2016, but he remained an unused substitute during the 3âÂÂ1 defeat. He signed a new two-year contract extension in March 2017.
The departure of second-choice left back Tom Field on loan for the first half of the 2017âÂÂ18 season allowed Chatzitheodoridis to make his senior debut with a start in the Bees' 3âÂÂ1 EFL Cup first round extra time win over AFC Wimbledon on 8 August 2017. He remained on the pitch until the 97th minute, when he was substituted for Henrik Dalsgaard. He played the full 90 minutes of the 4âÂÂ1 victory over rivals Queens Park Rangers in the following round and on 7 September, manager Dean Smith reported that Chatzitheodoridis would begin training with the first team on a regular basis. A season-ending injury to Rico Henry in late September saw Chatzitheodoridis become the backup to stand-in left backs Josh Clarke and Yoann Barbet during the first half of the 2017âÂÂ18 season.
On 19 January 2018, Chatzitheodoridis joined League Two club Cheltenham Town on loan and he was an ever-present starter in the remaining 18 matches of 2017âÂÂ18 season. Despite being contracted for one further season, Chatzitheodoridis was released by Brentford on a free transfer in July 2018.
On 23 July 2018, Chatzitheodoridis returned to Greece to join Super League club Panathinaikos on a free transfer. He finished a mid-table 2018âÂÂ19 season with 25 appearances and four goals. Prior to his 2019âÂÂ20 season being ended by an ankle injury, Chatzitheodoridis had made 26 appearances. He signed a new three-year contract in August 2020 and returned to match play in mid-January 2021. He made 8 appearances during what remained of the 2020âÂÂ21 season.
Despite frequently being named as a substitute, Chatzitheodoridis saw his playing time diminish and he made just six league appearances during the 2021âÂÂ22 season. He made one appearance during the club's successful Greek Cup campaign and received a winner's medal. Chatzitheodoridis transferred out of the club in June 2022 and made 66 appearances, scoring four goals, during four seasons at the Leoforos Alexandras Stadium.
On 27 June 2022, Chatzitheodoridis signed a two-year contract with Super League club Panetolikos. He made 50 appearances and scored three goals over the course of the 2022âÂÂ23 and 2023âÂÂ24 seasons, in both of which the club narrowly avoided relegation. Chatzitheodoridis departed the club at the end of the 2023âÂÂ24 season.
On 14 June 2024, Chatzitheodoridis signed a two-year contract with Super League club OFI on a free transfer. He made 35 appearances during a mid-table 2024âÂÂ25 season.
Chatzitheodoridis was an unused substitute for the Greece U21 team during two 2019 UEFA European U21 Championship qualifiers in October 2018. In June 2025, it was reported that Chatzitheodoridis was in discussions with the KFF about the possibility of representing the Kazakhstan national team.
Chatzitheodoridis was born in Greece to Kazakhstani parents.
