The report states that while the Germany international is Juve’s first choice, they have targeted other options as it may be difficult to sign the in-form midfielder from Dortmund.
Gündoğan recently played down reports linking him with a move away from Dortmund but opted not to rule them out completely.
“About my future? I currently have no idea. This is very, very far away,” Gündoğan told Sport1.
Dortmund sit in second place in the Bundesliga with 29 points in 13 games.
