Chelsea defender Ian Maatsen is interesting Borussia Dortmund.

The young Dutchman has spent this season on-loan in the Championship with Coventry City.

BILD says BVB are in the market for a new left-back and Maatsen fits the bill.

The 20 year-old Maatsen is under contract with Chelsea until 2024.

BVB are keen on Ramy Bensebaini (27) from Borussia Mönchengladbach, though Maatsen has emerged as a more affordable alternative.
