De Rossi was quick to defend the Manchester City striker on Wednesday, insisting there was no need to give him any special treatment.
"Mario is not a difficult character at all," he said.
"We treat him as one of the squad, nothing more, nothing less.
"There is no need for us to have a word with him, that is up to the coach, and we don't need to make any extra effort with him.
"On Sunday I shouted at him at half-time but that has happened thousands of times in my career with players.
"But there are no problems with him and there have never been any. He is a very good player."
