He explained it in the post-match press conference.
"My emotion was for everyone who loves this club. The fans, the players, the owners.
"This team spirit, we started building it in our summer camp in Portugal on the first day, and it's built up since then, day after day - this game is icing on cake.
"This victory belongs to everyone - it's a family win. Everyone played their part.
"I've had the honour of playing in more prestigious finals but the feeling of joy with everyone involved made me feel special really.
"This is a giant club without a trophy room to match the social importance of the club.
"I'm so happy for every single one of them. I will remember forever the people on the street, the ladies on the balconies, the kids lining the street. This to me means so much to me.
"Rome is a yellow and red city. In one year I feel it and tomorrow you will notice this on the streets, Rome is yellow and red.
"I made a little contribution to this and it makes me happy. My emotion was for everyone who loves this great club."
Rome is not Milan nor Turin. It's a totally different experience. You don't realize it until you're there.
