Brentford midfielder Toumani Diagouraga has reportedly submitted a transfer request at Griffin Park.
It was recently claimed that the 28-year-old had been the subject of a failed bid from Rangers, who are managed by ex-Brentford boss Mark Warburton.
It is believed that the Scottish Championship side are prepared to improve upon their original offer, and according to Sky Sports News, the Frenchman is also keen to make the switch.
Speculation has claimed that the Bees value Diagouraga at around £750,000.
