Sky Sports understands St Johnstone striker Francisco Sandaza is weighing up three offers from foreign sides.
Sandaza, who has scored 17 goals for Saints this season, is out of contract this summer and he could leave on a free transfer.
St Johnstone are desperate to keep hold of their top scorer, but no deal has been agreed as yet.
A number of clubs at home and abroad are monitoring Sandaza's situation at McDiarmid Park as they look to sign the Spaniard.
The former Dundee United man is thought to be weighing up pre-contract offers from three clubs - one in Spain, one in Greece and one in Cyprus.
Sandaza was strongly linked with a move to Rangers during the January transfer window, but a move failed to materialise.
However, St Johnstone face a real battle to keep hold of their prize asset this summer once his contract expires.
