passage: Soulis Papadopoulos
Papadopoulos moved to Cyprus and was appointed head coach of Cypriot First Division side Apollon Limassol. His stay however was brief, as he resigned from his post in September 2004 after a 6−1 loss from Alki Larnaca. He returned to Greece to take over Kastoria in the Beta Ethniki, but terminated his contract in just two days, due to personal reasons. Early in 2005, Papadopoulos took over as manager of Paniliakos, also in the Beta Ethniki before returning to Proodeftiki in the summer of 2005, managing the club for two seasons in the Beta Ethniki. At the end of the 2006-07 Beta Ethniki season, Proodeftiki finished in 16th place, thus being relegated to the Gamma Ethniki (the third tier of the Greek football league system) and Papadopoulos' contract with the club was terminated.
