Brighton midfielder Pascal Gross is being targeted for a return to Germany.
Sky Deutschland says Borussia Dortmund are showing interest in Gross.
The German giants are looking for a new defensive midfielder for next season and Gross is one of the names they are considering.
However, Dortmund has competition. Eintracht Frankfurt are also keen on the 32-year-old.
Gross, who has a contract until the summer of 2025, is said to have not yet made a decision about the future.
