I don't know what Mancini was doing out there, but Vieira and Adebayor are two players that you would rarely see starting in a league game.
Still, Juventus defended remarkably well for their low standards this season, for the first time they actually looked like a unit. Bonucci actually played well today, and Chiellini was very good too. Sissoko was a beast in the middle of the pitch, and surprisingly enough, he didn't lose the ball a lot today. He kept it simple most of the time and passed the ball to a nearby teammate.
Del Piero was dangerous on occasion, but age is obviously showing on him, he screwed up two very good counterattacks by being too slow, while Iaquinta screwed up two others because of his poor intelligence and decision making with the ball at his feet.
