Sky Sports understands Rangers are eyeing a move for Birmingham midfielder Morgaro Gomis.
Rangers are believed to be in the market for a new midfielder and Gomis is thought to be on Ally McCoist's wanted list.
Gomis is currently on the first-team fringes at St Andrew's with his only appearance coming as a late substitute in the Capital One Cup win over Barnet.
The 27-year-old made his name in Scotland after a successful spell with Dundee United between 2007-11, helping them win the Scottish Cup in 2010 before joining Blues on a free transfer last summer.
McCoist is thought to be a fan of Gomis and sees him as a key addition to his side as he looks to rebuild his squad after a number of departures this summer.
Blues boss Lee Clark could be willing to let Gomis leave for the right fee as it would free up funds for him to strengthen the squad elsewhere.
