The defender spent last season on-loan with Atalanta.
He said, “Now this call from the national team has arrived, and I'm proud of what I'm doing. My mentality has always been to grow daily. I'll continue to do so, without stopping.
“Italy and Juve? I know these tasks will be difficult, but I want to show that I can carry them out. I want to learn a lot. I'm a lad who always tries to learn from the best.
“I'll always guarantee my commitment on the pitch. Buffon? I'm sorry not to find him in the dressing room, but he's a legend and he's given so much to Italian football."
