Last season's Champions League finalists have reportedly identified the 19-year-old as a potential replacement for Mats Hummels, who has been touted as a summer target for Barcelona.
Ginter, a centre-back who can also play in midfield, was said to be the subject of interest from Arsenal in the summer transfer window, but stayed at Freiburg.
"I have told people many times I am very much at home at Freiburg," he told baden.fm radio station. "I enjoy it here. I have said this already last summer, on many occasions.
"This is why I have stayed on at Freiburg and that's why there is no room for any speculation."
The German Under-21 international has made 45 Bundesliga appearances for Freiburg, scoring twice in the process.
