Nice article, although Google translate doesn't do a great job with the translation. Like most Italian kids, it's clear he is very close to his family, and I hope he has some family here - it seems everyone I've ever met in Italy has some relatives here.
Funny you posted this today. After Mussini hit a nice driving one hander to beat the halftime buzzer, Mullin left the court with Federico speaking all the way, giving him advice on taking it to the hole in that situation. I was wondering how well Mussini understands English. By his body language, Mullin appeared to be advising him to take it a little deeper, because Mullin was accentuating an underhand finger roll as a finish. But it did appear the Mussini understands English well enough for Mullin to be speaking to him at length.
