Well, that may not have had much of the brilliant attacking play one would typically associate with a 4-0 win, but it was an impressively muscular and clinical performance from Juve.
Conte made a little adjustment to the 3-5-2 - with Asamoah playing almost as an orthodox left-back and the three centre-backs shuffling across a little - to make it play more like a back four, which made it clearer who was responsible for dealing with each of Klose, Candreva and Lulic and also made sure Juve wouldn't have their wingbacks pinned back preventing them having width higher up the pitch. Even with that change, Vidal was still required to play a pretty responsible game to free Lichtsteiner to attack up his flank.
Anyway, Juve looked very solid in their shape and through the first half it was very difficult to see how Lazio could hurt them, so it was just a question of whether Juve could find the goals to win the game, which they did - even though they never really threatened to open Lazio up in open play until they were 2-0 up and the game was virtually over.
Still thought Juve's forwards were far from brilliant, even though they managed a goal and an assist between them. They both gave the ball away a lot and the movement and decision making generally left a lot to be desired.
Thought Lazio looked unbalanced throughout. The introduction of Biglia to their midfield - as decent a player as may be - at the expense of a more mobile player doesn't look a great call at this point. With Hernanes not playing particularly high up, none of that midfield three really seemed to have the energy to get up the pitch to support Klose and, with Candreva and Lulic staying pretty wide, that left Klose looking pretty isolated for the most part. Be interesting to see if they stick with that midfield or if they bring Gonzalez or Onazi in. The two wingers really never left their flanks, which made their play rather predictable. They probably missed Mauri in that regard, as a player with the intelligence to drift into more interesting postions and provide closer support to Klose.
