I'm not sure whether Mutu will play or not, although I would like to see him on the field.
Vieira and Emerson will both probably be rather laid back in this game and help the defense deal with Totti and the Roma attack which is their strongest department. I am quite sure Roma will play attacking football, at least in the beginning. Therefore Capello will probably stick with a defensive lineup, only to sub in Mutu in the second half if necessary. I also think it depends a lot on the fullbacks who'll play. For instance I doubt we will see a Chiellini - Mutu left side.
It's nice having so many options.
