Bursaspor have told Rangers they will have to pay "serious money" to bring Kenny Miller back to Ibrox.
Light Blues' manager Ally McCoist is considering a move to re-sign the Scotland striker for what would be his third spell in Govan.
Miller was the top goalscorer in the Clydesdale Bank Premier League last season despite leaving in January, having struck 21 goals.
The Turkish club accept the player is unsettled and will consider a sale.
However, Bursaspor's director of transfers, Erkan Kamat, insists the club will not let him return to Scotland for anything less than a significant transfer fee.
"If the circumstances are right, if things are good, and the conditions are correct, then why not?" Kamat said.
"But Rangers have to pay serious money, a good transfer fee.
"If Rangers are opening the door, we can maybe settle something.
"It can happen but it is not just a case of opening the door, it's not that easy.
"At the moment I am not talking about his valuation. We will see what Rangers want to do."
Last month Rangers refused to entertain several offers from Bursaspor for defender Steven Whittaker but Kamat shrugged off his disappointment.
"I wanted to sign Steven Whittaker but Rangers always gave me a no answer," he added.
"In fact they didn't even get back in touch with me.
"I will have to make a plan. I can't say anymore just now. I will meet Kenny tomorrow, and then we will have a clearer picture."
Meanwhile, Andrew Little has thought about getting out of Ibrox for the last two and half years in order to kick-start his Rangers career.
The Northern Ireland international, 22, is currently recovering from two separate hip operations, but when fit he was used more often than not by former boss Walter Smith as a squad player.
Little has looked to go out on loan to get a regular run of games and will discuss the possibility with McCoist when he has fully recovered.
"My mind is more on getting fit, maybe a month down the road I will re-evaluate and maybe have a word with the manager and see what his plans are," he said.
"If I have a place here then great but I'm more than happy to go out on loan.
"I have been keen to go out on loan for the last two and half years.
"I feel as if I need 30 to 40 games a season.
"At the same time I want to play for Rangers and I want to play here.
"So if my chance comes I want to be here to take it."
