As I told you guys in this thread:
When Panathianikos wants a player they get him. Rudy Fernandez just personally confirmed to one of the largest papers in Greece in an interview that he is in talks with Panathinaikos Athens and that he hopes to be join the club soon. Basically, he's saying that within a very short time he expects the transfer to be officially completed.
So basically, he should be signing with Panathinaikos any day now.
