Sampdoria swoop for Fiorentina defender De Silvestri
The 24-year-old joins Doria on a loan deal with an option to be netted outright at the end of the current campaign.
"I immediately accepted this possibility, all it took was one phone call," the right-back said. "I have a great desire to kick-start my career.
"I've already got a taste of the Sampdoria fans over Twitter. I've received a lot of messages of support.
"There is a positive environment here and I will meet up with a lot of friends from the past. There is also my idol within the coaching staff - Angelo Peruzzi."
