Was unconvincing and struggled to hold on to a series of long range shots, noticeably Hernanes's swerving effort which he parried into Klose's path, allowing him to score.
It's no surprise that Juventus had the best defensive record in Serie A last season and Barzagli showed again why he is so valuable with his excellent reading of the game and good tackling.
Couldn't quite replicate his scintillating Super Cup performance but an assured display nonetheless. The Swiss wing-back's energy has ensured that he is a crucial component in Conte's formula.
Was the deepest of Juventus' central defensive trio but that did not stop him from stepping forward to execute two fantastic long balls to set up Vidal and Vucinic for their goals.
Another solid performance from the 29-year-old, who did an excellent job in marshalling Klose. The German did get on the scoresheet but ultimately failed to get the better of the Juventus No.3.
Five goals against Lazio now for Vidal in this calendar year alone. Showed that he is one of Europe's best box-to-box midfielders with a brilliant display of passing, tackling, close control and finishing.
Got into some promising advanced positions from left wing-back but never really looked a threat with his crossing. Was rarely exposed down his side.
A typical performance from the bearded wizard who helped Juventus to dominate the midfield with his intelligence and superb range of passing.
The France midfielder continues to shine in Marchisio's absence and on this performance, it seems unlikely the Italian will regain his starting berth. Produced a wonderful chipped reverse pass for Vidal's opener.
Seems to have thrived under the pressure of Tevez's and Llorente's arrivals. Worked his socks off up front and wasn't afraid to track back and help out the midfield. Deserved his goal.
Continued his promising start to his Bianconeri career with a typical hard-working performance. Dragged the Lazio centre-back pairing all over the pitch and was a constant menace with his dribbling. Made it three goals in three games with a brilliant placed effort.
Couldn't repeat his heroics from last season and was helpless to deny either of Juventus' goals. Will feel let down by his defence.
A horrendous error from the Argentine defender to allow Vucinic to score a third Juventus goal with ease. Looked out of his depth and failed to stick with his marker on numerous occasions.
Did a reasonable job against Asamoah but sometimes failed to track back. One of the few Lazio players who can take credit for his performance.
The Romanian defender struggled to contain the movement of Lichtsteiner and was at fault for failing to hold the line for Vidal's second.
Was a constant thorn in the Juventus defence with his neat footwork and ability to find space to shoot from distance. His swerving shot was parried by Buffon for Klose's goal. However, he did fail to track Vidal for Juventus' second and was sent off for stupidly handling the ball.
An anonymous performance from the utility man who performed as a right-wing back late on. Was often found trailing in Pogba or Vidal's wake.
Was effective at times down the left wing but will be disappointed with the accuracy of his crossing. Did a good job in limiting Lichtsteiner's freedom.
Was dominant in the air for Lazio at both ends of the pitch but was forced out of position on numerous occasions by the intelligent movement of Tevez.
Seems to be struggling to make the adjustment from Belgian football to Serie A. Didn't know whether to sit in front of the back four or close down Pirlo, both to which he did to minimal effect.
Impressive and determined showing from the former Juventus man, who caused problems with his teasing crosses and long range shooting. Didn't deserve to be on the losing side.
Didn't have the greatest service but nonetheless took his chance when it came, showing great anticipation to react quickest to poke Hernanes' spilled shot past Buffon.
