He was awful when he played earlier in the season and didn't bring any leadership...so the Kompany you're imagining is a fantasy.
That is your opinion and I have mine. At Palace away when he lasted the full game he was very good and was a real leader on the field as well. A fully fit Kompany adds so much to the team in terms of defensive organisation and leadership. If he isn't fully fit get him out of the squad, if he is get him into the team.
