Skysports.com understands a number of clubs are chasing Hibernian star Derek Riordan.
Riordan has recaptured his best form this season after a disastrous two-year spell at Celtic.
The 26-year-old, who is in his second spell at Easter Road, has scored six goals so far this term and won his place back in the Scotland squad after catching the eye in Edinburgh this season.
Riordan has just 18 months to run on his current deal and as yet no talks over a new contract have taken place alerting clubs to his possible availability.
German outfit Hertha Berlin, Greek giants Panathinaikos and long-term suitors Lokomotiv Moscow are all thought to be tracking the versatile forward.
A number of English clubs are also keeping tabs on Riordan and more scouts from interested clubs are expected to watch the skilful attacker against Kilmarnock this weekend.
Hibs would be loath to lose their star performer as they look to maintain their title bid, but they could face a fight to keep hold of him if one of Riordan's suitors make a firm bid for his services.
