Overview
- Reports from BILD say Chelsea have begun negotiations and held serious talks for 18-year-old centre-back Karim Coulibaly, with no formal bid yet.
- Werder Bremen value the defender at about €45m (£39m) and Newcastle, Napoli and Marseille have also shown concrete interest.
- Coulibaly has broken into Bremen’s first team this season with around 20–22 Bundesliga appearances and he is under contract until 2029.
- Chelsea are lining up summer reinforcements at centre-back after a failed January move for Jeremy Jacquet and while managing Levi Colwill’s return from an ACL injury.
- Yahoo Sports and Football Talk relay the BILD reporting, underscoring that this is early-stage negotiation rather than an agreed transfer.
