Polish international left-back Seweryn Gancarczyk is rated at £750,000 and has played most of his career in the Ukraine with Metalist Kharkiv.
Celtic have also invited American international goalkeeper Brad Guzan to their training headquarters next week.
Guzan, 23, is valued at around £1m and has played four times for the USA.
