The way some (or it seems, most of the vocal ones) fans treat him and Stones, I'm not surprised they'd want to leave.
Just take a look at the comments for one of his pictures on Rom' official Facebook page:

He's 23 ffs. As if ambition is a crime. You want him to say negative things about the club? Treat him like this and that's what you get.
If he stays, great, we don't need to look for a replacement. If he leaves, he leaves and we get a big bag of money. People need to grow up and stop being so bitter.
