Czech Republic forward Patrik Schick is still not ready to play for Roma because of a thigh injury, coach Eusebio Di Francesco said on Monday.
Di Francesco added that Roma, who host Chelsea in Champions League Group C on Tuesday, were investigating their recent spate of injuries and he did not believe they were just a coincidence.
Schick has only played 15 minutes for Roma since signing from Sampdoria at the end of the transfer window and has been out of action since mid-September, although he has been on the bench for their last three games.
