Ludogorets defender Georgi Terziev is being tracked by Inter Milan.
Inter will have scouts attend the league playoff between Ludogorets and Litex Lovech to check on Terziev.
The 23 year-old defender can play at centre-half and fullback. He has just broken into the Bulgarian national team this season.
Terziev is tied to Ludogorets until 2017 and is rated at a knockdown €3 million.
Inter won't make a final decision on the defender until after the playoff.
