I think he is fit enought, but Conte will fear about his whole match performance. After last Roma match he said about Asamoah that his absense was bad for his feeling of the system of play.
I agree with Dan10. Bring him on as a sub, so that he gets a run. We don't want to put too much pressure on an importtant player like him. Besides, he may be targeted by the opposition as he is just back from injury; - we don't want him injured again so soon!
