I asked for autographs from a bunch of Juve players and Raul too once. I had this expectation that it would be so cool to have. Then I left those pieces of paper somewhere in my house and I've never needed them for anything. I've no idea what the point was.
It's at least how I see that. I never asked for any nor I will. I know I heard some people mentioned that when Roma came to Belgrade but no thank you. Watching the match was enough.
