Mladenovic has suffered with injury in his short time at Rangers

The midfielder was signed for �1.2m from Red Star Belgrade in the summer.

Now, after just six starts for Rangers, his agent says he must find a new club before the end of the month, although Rangers deny such an instruction.

Ken Anderson told the Daily Record: "After Rangers made it clear to us he can move, we have been in talks with clubs in Germany and Russia."

Mladenovic has been plagued by injury since his arrival in Scotland, but Rangers have signed Thomas Buffel from Feyenoord and are chasing Blackburn Rovers' Barry Ferguson to improve their midfield.

"He has no desire to go and wanted to stay and fight for his place," said Anderson.

"He has been unlucky with injuries and feels he has a lot to show.

"We have also had one or two English Premiership clubs asking about the size of the fee and salary. He won't be short of offers."
