Nikola Katic, a former footballer, has apparently received an offer from Rangers.
The defender has 18 months left on his FC Zurich contract.
The 28-year-old is reportedly pushing to leave the Swiss team.
With his defence beset by injuries this season, Philippe Clement is still rumoured to be seeking to reinforce his team before Monday’s transfer deadline.
Rafael Fernandes, a Portuguese defender who came on loan from Lille in France, is the lone newcomer to Ibrox this month.
The sole known first-choice centre-back is Robin Propper, as Leon Balogun, John Souttar, Dujon Sterling, and Neraysho Kasanwirjo are all presently sidelined due to injury.
Recently, Rangers needed squad choices, so they elevated Leon King and Clinton Nsiala from the B team.
Additionally, it appears that the Scottish Premiership team would consider Katic as a backup.
Rangers reportedly made an offer to the strong centre-back, according to Swiss media site Watson.
Former Swiss international and current commentator Pascal Zuberbühler argues Zurich needs to ask for a fee if Katic leaves.
“Katic is employed at FC Zurich,” he informed Blue Sport. Is their offer solid? FC Zurich is the owner of the player.
“As a sporting director or president, I want to see from a club that we want Mirlind Kryeziu, we want Nikola Katic – for this and this price.”
