The midfielder was back for yesterday's victory over Hellas Verona, however, and was asked about staying long-term in the post-match mixed zone.
He told TMW: "I don't know yet. I didn't play too much and I don't know if I'll stay. I need to work harder and play, understanding my teammates and scoring lots of goals.
"I still like Roma a lot, I play in a fantastic team and we can do together so many beautiful things this year, let's work to win them all, let's see where we finish.
"The Serie A is different, but I like it. I get on well with the preparation of the games and the training. I have to do everything possible, on a personal level, to show my qualities here too."
