Apostolos Konstantopoulos

Apostolos Konstantopoulos came through the academy at Panetolikos, joining the Greek club's youth ranks in 2007 and working his way to a first-team debut in 2019. He stayed with Panetolikos until the summer of 2021, when Beerschot signed him for a fee reported in the Belgian press at around €500,000.

Konstantopoulos was part of the Beerschot side that won the Challenger Pro League in 2023/24.

His stay in Poland began as a free transfer. Konstantopoulos joined Raków Częstochowa on 1 July 2025, but by the end of January the following year he had moved on again, this time to Jagiellonia in a permanent deal rather than a loan. Weszło reported that Raków kept a sell-on percentage from any future transfer. He signed with Jagiellonia through the end of the 2026/27 season, with an option to extend by a further year.

He made seven Ekstraklasa appearances for Jagiellonia in 2025/26, then added two more league games and two Europa League qualifying ties once 2026/27 got under way.

Konstantopoulos has yet to be called up to Greece's senior side, though he came through several youth levels: six caps for the under-16s in 2017 and 2018, two for the under-17s in 2019, and fourteen for the under-21s between 2020 and 2024.
