The German international has been linked with a possible reunion under former manager Jurgen Klopp at Anfield, while United are also keeping track of his progress.
But the playmaker insists he is still devoted to Dortmund and revealed he sees himself remaining at the Bundesliga club next season.
“This is an issue that is always floating around,” said Gündoğan
“I am very happy with BVB and feel very comfortable here.
“Of course, I can imagine remaining here beyond the end of the season.”
