Konstantinos Triantafyllopoulos

On 30 September 2012, during a Super League match vs. Asteras Tripolis, Triantafyllopoulos made his debut for Panathinaikos. In his first season, he became a mainstay in the centre of defence. At the end of the season, Triantafyllopoulos signed a contract extension for three years. On 22 January 2016, Triantafyllopoulos signed a 3.5-year contract with Asteras Tripolis, despite the rumours that he will sign to Panionios, as part of Olivier Boumale transfer to Panathinaikos. His former club will keep a percentage of the profit from his next transfer. On 13 June 2019, he joined Pogoń Szczecin on a two-year deal. On 10 August 2019, he scored his first goal with the club in a 1–0 home win game against Wisła Kraków contributing the most to his team's win. On 20 May 2021, Pogoń announced the renewal of the 28-year-old Greek defender's contract for one year with the possibility of extending their cooperation for another season. On 19 July 2023, Triantafyllopoulos moved on a free transfer to another Ekstraklasa club Górnik Zabrze, with whom he signed a two-year contract. On 26 June 2024, he terminated his contract by mutual consent.
