Former Rangers manager Walter Smith thinks striker Kris Boyd will be a potential signing target for the club now that he has left Eskisehirspor.
"I'm sure, if he's available, he'll come into their thoughts," said Smith.
"He scored an awful lot of goals for Rangers and was a good player for Rangers over the years.
"He's left because he was offered a better deal in England at the time and again in Turkey. He would be an obvious one to have a look at."
The theory raised is that Boyd will be seen as a relatively cheap replacement for Nikica Jelavic should the Croatia striker be sold in January as no transfer fee for the Scot would be required after he left the Turks over a contract dispute.
Speculation is again linking the 26-year-old, for whom Leicester City had a bid rejected in the summer, with a move away from debt-stricken Rangers.
But Smith said: "During the last three years or so, at every transfer window, every player at the club was for sale and we never lost very many.
"Those that we did lose were due to run out of contract in the summer.
"We've lost in the past in the January transfer window and were disappointed in doing so and maybe managed to handled it.
"But for Rangers to hold on to any of their players has been important and the loss of Jelavic is something they could well do without."
Smith's departure from Rangers, and his handover to assistant Ally McCoist, coincided with the takeover by businessman Craig Whyte and the former manager believes that the club has been stabilised after that period of upheaval.
"You have to give everyone time to settle down at Rangers," said Smith.
"It would be an awkward period for any club to have new owners, new managers, new players coming in and trying to integrate into the team.
"There are always awkward situations and I feel Rangers have handled that very well in the opening half of the season.
"You have to prove you can carry it on under the pressure of the second half."
Smith praised his protege McCoist, whose side sit four points clear of Celtic at the top of the Scottish Premier League ahead of the 28 December derby between the Glasgow rivals.
"I think he's handling it well," said Smith. "European games were disappointing for him, the way it went, but the league form has been terrific.
"From a Rangers point of view, the next few games are vitally important.
"If you find yourself in the second half of the season at the top of the league, that's a big thing psychologically.
"The championship races in recent seasons have been very tight and I don't see this one being any different."
