Borussia Dortmund are tracking Manchester City's Bersant Celina, sources close to the player have told ESPN FC.
Midfielder Celina is on a season-long loan at Dutch club FC Twente, where his performances have sparked Dortmund's interest.
The Kosovo international has scored three goals in six games and made another, with scouts for the Bundesliga club now monitoring him.
Celina is highly regarded at City, having worked his way through the ranks since joining from Norwegian side Stromsgodset in 2012.
He made his first-team debut in January and added three further appearances in all competitions, creating a goal for Sergio Aguero after coming on as a substitute against Leicester.
