The right-back moved to Ibrox on loan from Aston Villa in the summer with a conditional obligation to buy attached – believed to hinge on the appearances he makes this season.
However, he has so far been limited to one start and one substitute appearance in the Premiership, as well as to cameos from the bench in Europe.
He was slightly hampered by injury early in the season, while Dujon Sterling has cemented the right-back slot as his own for now.
Media in Serbia are now speculating that other clubs are willing to take Nedeljkovic on loan instead – with any deal obviosuly having to wait until January.
The 20-year-old still managed to earn his 12th cap for Serbia in the defeat to the Netherlands yesterday.
In their player ratings, Serbian outlet Mondo: “There is no playing time for him even in Rangers, so Kosta is still wanted by foreign clubs.”
He previously had interest from Spanish side Osasuna, among others, before choosing Ibrox.
With Rangers’ results having picked up in recent weeks, manager Derek McInnes seems to have come across a system and personnel he can trust for the moment.
Speaking on Nedeljkovic’s fellow Serb Vanja Dragojevic, he said: “We have settled in recent weeks on a system.
“The same back four, same midfield two. Some form of three behind a main striker or a front two of some sort.
“We’re just trying to find a bit of consistency of selection and consistency of results, which we’ve seen.”
