The 26-year-old had talks with the Ibrox side as far back as early July and Ally McCoist insisted yesterday he could yet become a Rangers player.
However, Pandza said last night: "Nothing's happened. Everybody says 'wait, wait, wait' - all summer we waited and in the end, nothing.
"It's a new situation that they want to sell some players but they are limited with the budget. When they've been talking about [signing him] for three months and haven't done anything then that's not professional.
"I'm a little bit disappointed. To be honest I don't believe something is going to happen. If they don't want me then don't say anything about me."
