He left the Giallorossi for the Sardinians this summer.
"Playing Roma will certainly have an effect on me," he told La Repubblica.
“I don't know what to expect. I hope they don't whistle me. It's difficult becoming a Roma icon after Totti and De Rossi.
“But certainly, I'd thought about ending my career at Roma. I was happy there, I gave my soul, I had everything I wanted.
“Leaving was a great disappointment, but in life paths sometimes cross. Things have become a bit more difficult for them because they have only a few players with personality.
“It takes b***s to play for Roma. Everything is beautiful there, but when things go wrong and the fans whistle you, you must have character.
“Strong players are able to block things out. There's the radio, newspapers... but come on, they spout nonsense. These things are everywhere.
“I never thought about the Scudetto. I haven't won anything, but I don't care: I wouldn't change anything about my career. It's better to be where I'm appreciated.
“It's crazy having to sell players by force. That way, a club will never win anything and players are transformed into numbers."
