Croatian pair Dario Srna and Dario Jertec are being strongly linked with moves to Paris Saint Germain and Le Mans respectively.
Shaktar Donetsk midfielder Srna (pictured) is keen to move to Ligue 1 and PSG are ready to step up their bid to sign him.
Director of sports Alain Roche has already held talks with the player and are rumoured to be willing to offer é¼4million (£2.7million) for his services.
Srna could join Marcelo Gallardo in moving to the Parc des Princes during the January transfer window.
Meanwhile, Le Mans are tracking Nk Varteks star Jertec.
The 21-year-old is high on coach Frederic Hantz's wish-list and has been watched by Le Mans scouts on more than one occasion.
"We are watching but may not follow him immediately," chairman Henri Legarda told L'Est Republicain.
