Montpellier and Valenciennes are believed to be leading the chase for FC Zurich midfielder Dusan Djuric.
The French duo have identified the Sweden international as a top target for the winter transfer window.
The 27-year-old's contract in Switzerland is running down and his current employers are reluctant to lose him as a free agent.
Zurich are open to offers and have confirmed that a number of bids have been received.
Montpellier and Valenciennes form part of the chasing pack, but they face competition from across Europe for Djuric's signature.
"It's correct that we have two serious offers and many interested clubs," Djuric's agent Oliver Cabrera told Fotbolldirekt.se.
"Two from France, one from Germany and one from Russia."
