Ally McCoist has refused to rule out making a move to bring Kris Boyd back to Rangers, with the striker available as a free agent.
The Scotland international netted 127 times for the Gers during a productive four-and-a-half-year spell between 2006 and 2010, becoming the SPL's leading scorer of all-time in the process.
There is a chance he could be heading back to Ibrox, with McCoist in the market for a new frontman.
With youngster Kane Hemmings sidelined until January, Kyle Lafferty struggling with a knock and question marks hanging over Nikica Jelavic's future, the Gers are ruling nothing out.
"I'm in no position to rule anyone in or out," McCoist said on Thursday.
"Our attacking line certainly needs strengthening."
Boyd left Rangers for Middlesbrough at the end of the 2009/10 campaign, but struggled to reproduce his prolific form in English football.
He made just 29 appearances for Boro before going on to score six times in 12 outings for Nottingham Forest during a loan spell last term.
The 28-year-old took the decision to take on a new challenge in Turkey over the summer, but endured a frustrating time with Eskisehirspor.
He saw just 76 minutes of action for the club, during which time he went unpaid, and ripped up his contract on Monday.
