According to The Scottish Sun, Sweden international left-back Martin Olsson held talks with Rangers last week as the club step up their search for a replacement for the departed Lee Wallace.
Andy Halliday and Jon Flanagan have both featured in the position, but manager Steven Gerrard is keen on a primary left-back after Borna Barisic failed to impress.
Olsson left English Championship outfit Swansea last month after his contract expired, and the free agent is currently considering his options as he finds a new club.
Rangers already have a suitor to contest with for the signature of the 31-year-old in Nottingham Forest, but beating competition and landing the Swede will be huge for Gerrard’s side.
