I'm not sure what the thought process was to put Vidal as an attacking midfielder, clearly looked out of position. I didn't like how we started, Matri should have had another forward next to him (in place of one of the wingers) if the team was going 4-3-3 to start with. Sort of like below. Or just keep the 4-2-4 formation from the first three games.
Marchisio-Pirlo-Vidal
Winger/FW-Matri-Winger/FW
Few things I didn't like. In the dying minutes Grosso runs half the pitch and tries the shot, when there were two players in the box. Vidal's clumsiness only outdone by Chiellini, both really had a few awfully lazy pieces of play. Krasic almost gifted them a goal as well late on. Good players were probably Marchisio and Barzagli for the most part.
Juventus were quite lucky that Catania were wasteful, they had the best opportunities and could have had 3 goals in that game.
