The 26-year-old joined VVV-Venlo last summer on loan from Werder Bremen, and has enjoyed a decent campaign for the Dutch side.
The report claims that Celtic sent scouts to watch the former German under-20 international in action in VVV-Venlo’s Eredivise clash with FC Twente on Saturday.
The match ended 0-0, but Thy did a decent job. He has scored seven goals in 28 games this season, including a hat-trick against Heracles.
