We continue our detailed look at each of our Conference League opponents by focusing on Panathinaikos, one of the most heralded teams in the competition.
Chelsea have storied history in Athens, beating Real Madrid in the Cup Winners' Cup final there in 1971, after a replay. We also met Panathinaikos' great rivals Olympiacos during our 2007/08 Champions League campaign.
Panathinaikos are a fresh face who we will play on Thursday 24 October, away from home. You can see the rest of Chelsea's Conference League fixtures here.

They overturned a 2-1 first-leg deficit against Lens by winning the return game 2-0 in Athens. Their first league phase fixture ended in a 1-1 draw away to Borac of Bosnia and Herzegovina.

Dutch defender Bart Schenkeveld is their experienced captain, while Facundo Pellestri joined from Manchester United this summer.
Notable former players Five Panathinaikos players were part of Greece's victorious squad at Euro 2004, notably defensive midfielder Angelos Basinas and right-back Giourkas Seitaridis. The latter was part of a formidable defence and was named in the team of the tournament.
