Lee Wallace
Rangers captain Wallace is in danger of losing his first-team slot at left-back following the rise of Malta international Myles Beerman during the second half of the season.
Leeds’ defence is currently lacking in leadership following the loss of Swansea defender Kyle Bartley, who is unlikely to return to Elland Road following the resignation of manager Garry Monk.
Bringing the Gers skipper in to replace Taylor would be a huge coup for Leeds.
