Borussia Dortmund are turning down offers for 17-year-old midfielder Matis Albert, despite interest from Chelsea, Manchester City and Paris Saint-Germain, according to transfer insider Ekrem Konur.

Konur reported on social media that the clubs are interested in the teenager, who is regarded as a sought-after prospect in the European transfer market. Dortmund’s leadership has rejected all proposals for Albert, including loan deals.

The American player’s contract with Borussia Dortmund runs until the middle of next year. His market value is estimated at five million euros by Transfermarkt.
