Borussia Dortmund have held talks with Chelsea defender Ian Maatsen over a January move.
The 21-year-old is losing the battle to convince Chelsea of his long-term worth, having started just one Premier League match this season despite the club’s ongoing injury crisis.
Chelsea are open to selling Maatsen, who has struggled for minutes under Mauricio Pochettino and has entered the final 18 months of his contract.
