Yes, I also heard the same thing. There was a discussion on a couple of forums between Zvezda fans whether it was a good idea..The funny thing is, nobody from Zvezda ever officially confirmed those rumors, but the fans still continued the "big debate"..

I myself seriously doubt it, above all because I don't think Zvezda has that kind of money to spend, otherwise they wouldn't be selling their best players again (Dudic and Bunjevcevic)..
So, as a conclusion, I doubt it..
Cheers!!
