Borussia Dortmund is exploring a deal to sign Chelsea defender Joshua Acheampong, with several other clubs also monitoring his situation.
Acheampong, 19, is seeking more first-team opportunities to further his career progression.
Suitor clubs believe Chelsea may be willing to sell Acheampong for £35m, despite previously rejecting loan offers and approaches.
Tottenham Hotspur and Newcastle United are among the Premier League clubs interested in Acheampong, having observed him for some time.
Chelsea's potential willingness to sell could be influenced by Financial Fair Play regulations and their interest in acquiring players from interested clubs, such as Jamie Gittens from Dortmund.
