According to Bild, Jerome Boateng is on the verge of joining Juventus.
There are even reports in Bild that Boateng skipped training and a photoshoot today, so could fly out to Turin within hours.
Chiellini tore his anterior cruciate ligament in training and is expected to be out for around six months.
According to Tuttosport, Calciomercato24.com and Das Bild, Juventus' first target is Boateng, who had already been linked with the Bianconeri before they pounced for De Ligt over the summer.
Sky Sports journalist Marc Behrenbeck reported on Sunday that Jérôme Boateng is considered by Juventus as a replacement for the injured Chiellini. First contact between the two clubs has already taken place.
