M. De Sanctis
Could have did better for Lazio's first as Mauri's shot was weak, but generally did well today. Cannot be blamed for the other two goals.
Had a great game at the back and even got forward on a couple of occasions. Only notable mistake was his failure to close down Mauro Zarate in the build-up to Salvatore Aronica's own goal.
Struggled for large parts of the game and his own goal summed up his performance. A game to forget for the defender.
Offered a lot of running and put much effort into this game. Assisted Cavani's first and ran his socks off for his team.
Lost possession too often and in dangerous positions, too. Caught flat-footed for Stefano Mauri's opener and should take some blame for Dias' goal.
Not one of his best games, but also not one of his worst. Scored an unlikely goal, but generally offered very little in attacking sense.
Pretty much invisible today. Made a few good passes, but was very isolated and failed to influence the game in any way.
Made a few good passes and tackled well. Covered a lot of ground, but offered nothing breathtaking from a creative sense.
Spent most of the time on the ground, misplaced a few passes and failed to stamp his authority in the centre of the pitch.
He failed to impress from open play today, but was impeccable at set-pieces as Napoli's first two goals came from free-kicks taken by him.
Zlatan Ibrahimovic might have something to say about it, but Cavani can claim to be the best striker in Serie A. Bagged a hat-trick and was once again the decisive factor for Napoli.
Horrible game from Muslera. Could have done better for all but one goal. Failed to react for Dossena's effort and Cavani's equaliser, and was poorly positioned for Cavani's third.
He was harshly sent off, but in truth that does not overshadow his poor performance. Conceded a silly penalty and failed to intervene for Dossena's goal. Struggled against Lavezzi and Edinson Cavani.
Had an impeccable first half and scored a great goal after the break. Should take some blame for Cavani's first and third as he failed to intervene.
Did not join the attack as often as he generally does, but did well defensively, barring his error in the build-up to Andrea Dossena's goal.
Very good game from the ex-Manchester City left-back. Inch-perfect delivery for Andre Dias' goal and was rock-solid at the back.
Started poorly, but improved as the game progressed. Had a few good runs and made a couple of nice passes.
Failed to influence the game today. Offered virtually nothing in attack and generally had a very poor game.
Scored a wonderful, yet lucky goal, and generally played well. Missed a glorious opportunity in the 33rd minute when he put his finish wide of the left post. Sprayed the ball well.
Had a goal wrongly disallowed. He was superb today as he bossed the midfield and certainly did not deserve to end up on the losing side.
As it often happens, Zarate tried to do too much by himself today. Lacked the needed confidence to score and failed to spearhead the attack, although he did have a hand in Stefano Mauri's opener.
Drifted in and out of the game, and picked up a needless second yellow card. Was too reckless with his tackles and generally had a very poor game.
