The teenager has signed a six-year contract with Chelsea.
Cesare Casadei joined Chelsea from Inter Milan earlier last week in a deal worth up to €20m.
He initially won’t be a part of Chelsea’s first-team but will work his way up according to Thomas Tuchel.
Thomas Tuchel will give the new midfielder some time to adapt and settle at Stamford Bridge.

“First of all, we need to give him time and not get overexcited because that would not do him a favour,” said the German.
“He’s a box-to-box midfielder, very strong with his head, very physical for his age but at the moment it’s important that he learns the language, he learns what Chelsea is all about and understands the culture and the principles to live and play for Chelsea.
“Then we will try and bring him to first-team training and open the doors for him. In the end, he needs to step through himself.”
