I'm looking to write to Marco Tardelli, the Italian footballer who played for Juventus and won the World Cup in 1982. I haven't been able to find any good contact information on here. I've found the address for writing to Juventus, but some threads on here have led me to believe that many responses received after writing to the club aren't genuine. Is there a better way to contact him than through the main club address? For reference, the one I've found on here is as follows:

Juventus
Juventus Football Club S.p.A.
C.so Galileo
Ferraris 32
10128 Torino
Italy

Though an autograph would be nice, I'm not looking to solely collect. I have a friend who's just a really big fan of his, so I was going to try to write and see if I could get some kind of a response. I don't have any trades of any kind to make. I'm not an autograph collector. This is just something that I thought would mean a lot to my friend, getting to hear back from him if he's willing, and any address would be kept otherwise private if desired.
