Danilho Doekhi claims Rangers are tracking his Vitesse Arnhem situation.
But the Dutch defender admits he'd prefer to move on from his club side in summer rather than this window.
Doekhi, 23, is out of contract in six months and would be free to discuss terms with Gio van Bronckhorst and Ross Wilson right now.
He could be an ideal replacement for Connor Goldson, who is also on an expiring deal with a fresh set of terms as yet unsigned.
Tying the Englishman down for longer would be the favourable outcome but it seems the Ibrox recruitment team are planning for the future after Doekhi told regional broadcaster Omroep Gelderland he knows of interest from Glasgow.
Asked specifically about Rangers, he answered: "They follow me, but there are several clubs."
It's up to the Arnhem side to accept or reject any January bids for their captain, who was speaking from a warm-weather camp in Portugal during the Eredivisie's winter break.
But he said he'd prefer to change clubs in the summer.
Doekhi added: "The fans don't have to worry about me leaving yet.
"But there are certainly things at play that you philosophise about yourself sometimes.
"As far as I know, no club has come knocking on Vitesse's door yet. I'm not so much in favour of a winter transfer, but of a departure in the summer."
If Rangers do make an approach, one club that won't be in competition are Croatian giants Dinamo Zagreb.
"We have no contact with them anymore," Doekhi revealed.
