Chelsea have made an enquiry for Inter Milan midfielder Cesare Casadei, 19, as they continue talks with the Italians over defensive options too.
While yet to make his Serie A debut, Sky Sport in Italy believe Inter will let Casadei go if the Blues offer €10million (£8.3m).
The talented teen has been compared to Italian midfielder Marco Verratti, who has proven himself to be one of the best players in his position during a decade at PSG.
Inter are set to respond to Chelsea's approach in the next few hours, and may enter into negotiations with a counter offer.
