Chelsea have reportedly made a bid of around €40 million (£35.6 million) plus add-ons for Juventus defender Mattia Caldara.
According to Corriere dello Sport (h/t Calciomercato's Kaustubh Pandey), the offer follows a visit from Chelsea director Marina Granovskaia to Italy, with the Blues having turned their attention to Caldara from his Juve team-mate and fellow centre-back Daniele Rugani.
It's said the Bianconeri want a fee in the region of €50 million (£44.5 million), but Chelsea could try to meet them in the middle.
