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.
Hakim Ziyech has signed a five-year deal to join Ajax from Twente for a fee in the region of €11 million.
Ziyech, 23, is a Morocco international who was reported to be on the radars of Everton, Arsenal and West Ham this summer.
But the attacking midfielder told Ajax's official website he decided he wanted to remain in the Netherlands and pursue his goal of winning the Eredivisie title with the 33-time Dutch champions.
