Rangers are chasing Manchester City fullback Danny Mills.
The News of the World says the ex-England defender, 30, who was on loan at Hull last term, wants to quit Eastlands to resurrect his career.
With two years left on his contract, City are believed to be ready to let him go for around £1million, which will suit cash-strapped Gers as they bid to catch up SPL champs Celtic.
Mills' advisor, Neil Featherby, said: "we've had plenty of interest in Danny but are keeping our options open."
