The Greek club have already talked with his agent, and Drobny says that he would be keen on a move
Drobny told Sportday: "My agent has already had contact with Olympiakos officials.
"I can't say anything more, because I don't know anything more.
"I have to say that playing in Greece with Panionios, I managed to create my name and become well known in football, so I will have them in my heart forever.
"But if I am going to go back to the Greek league, I would only like to play for Olympiakos. I have always liked the club and especially their fans.
"They have the most passionate supporters in Greece and of course the fact that Olympiakos play in the Champions League every year is a big motivation."
