Serie A play started with one match Saturday evening, to be followed by a busy weekend schedule.
Eight matches were scheduled for Sunday, including Inter Milan's trip to Napoli. Then, on Monday, AC Milan were set to host Roma in another marquee matchup.
Napoli closed the gap on second-placed Roma to two points with a 4-2 win at home to Inter Milan on Sunday.
Five of the game's six goals came in a busy first half. Gonzalo Higuain put the hosts ahead in the ninth minute, but Inter equalized 10 minutes later. Fredy Guarin crossed from the right and Rodrigo Palacio tricked the defense with a dummy before Esteban Cambiasso swept in to make it 1-1.
Napoli needed just four minutes to retake the lead through Dries Mertens, who fired home after Blerim Dzemaili had held up play along the edge of the box. Dzemaili then made it 3-1 in the 41st minute as Napoli broke forward with pace.
Yuto Nagatomo pulled one back for Inter on the stroke of half-time, but Jose Callejon sealed the victory for Napoli in the 81st minute, tapping in from Lorenzo Insigne's cross.
Napoli still had time for another, but Inter goalkeeper Samir Handanovic saved substitute Goran Pandev's penalty in second-half stoppage time.
The win sent Napoli up to 35 points, two behind Roma in second place. Roma play at AC Milan on Monday. Inter remained fifth with 28 points.
On target: 9-5
Carlos Tevez hit a hat-trick and assisted the fourth goal as Juventus made up for their midweek Champions League disappointment by routing visitors Sassuolo 4-0 on Sunday.
Tevez scored in the 15th, 45th and 68th minutes for Juve, who have won eight straight league matches. He assisted the other goal, scored by Federico Peluso in the 28th minute.
With the win, Juventus moved six points clear of second-placed Roma atop the table. Roma play at AC Milan on Monday. Juve were knocked out of the Champions League this week after losing at Galatasaray in their group-stage finale.
On target: 8-0
Goals from Josip Ilicic, Borja Valero and Giuseppe Rossi saw Fiorentina ease to a 3-0 win over struggling Bologna on Sunday.
Ilicic took advantage of a defensive error in the 13th minute before drilling the ball home for the opening goal for Viola.
Fiorentina were in total control of the match when Valero added the second on the half-hour mark. The Spaniard took one touch to control a through ball into the area from Rossi, and grabbed his fifth goal of the season with a curling effort.
In the 64th minute, Rossi sealed the win for Fiorentina when he controlled a ball over the top from Valero, and then sent a high lob over Bologna goalkeeper Gianluca Curci.
On target: 8-4
Torino claimed their second away win of the season with goals from Alexander Farnerud and Ciro Immobile at Udinese on Sunday.
The visitors opened the scoring three minutes after the interval when Gabriel Silva's mistake allowed Torino to counter attack at pace.
And Alessio Cerci found Farnerud with a through ball, which the Swedish forward lobbed over Udinese goalkeeper Zeljko Brkic.
Udinese almost equalised in the 67th minute through Nico Lopez, but his shot flew wide.
That missed proved costly, though, as Torino added a second goal moments later when Mattia Darmian raced down the right wing before pulling the ball back for Immobile to head home.
On target: 3-3
Miroslav Klose scored twice on his return from injury to fire Lazio to a 2-0 win over struggling Livorno on Sunday.
The Germany international had already struck the post when he opened the scoring in the 19th minute.
Hernanes played the veteran forward into the area, and after seeing his first shot blocked, Klose pounced on the loose ball to give Lazio a 1-0 lead.
Seven minutes later, Klose was on target once more with Hernanes again involved when his effort was blocked by a Livorno defender.
The former Bayern Munich striker was on hand to snap up the rebound to drill home for Lazio.
The win ended a run of seven matches without victory for Vladimir Petkovic's team.
On target: 5-1
Eder scored the only goal of the game as Sampdoria claimed a 1-0 win at Chievo on Sunday.
The Brazilian headed home the winner in the 16th minute when he connected with a corner from Angelo Palomobo after out-jumping Chievo defender Nicolas Frey.
Alberto Paloschi squandered a great chance to claim an equaliser for Chievo three minutes before the end, but he failed to convert a Cyril Thereau cross.
On target: 6-2
Giuseppe de Luca hit a last-gasp equaliser to give Atalanta a share of the points at Genoa on Sunday.
Andrea Bertolacci had given the home side a 67th-minute lead when he seized on a loose ball in the area to drill the ball home.
But Atalanta refused to give up and were rewarded in the final minute of injury-time when DeLuca slotted home after collecting an excellent through ball from Luca Cigarini.
On target: 3-4
Parma and Cagliari played out a drab 0-0 draw at the Ennio Tardini on Sunday.
Parma goalkeeper Antonio Mirante made a number of saves to deny Nene and Daniele Dessena in the first period.
The home side showed more intent after the interval, and Vlada Avramov forced a great save from Jonathan Biabiany.
But the game fizzled out from that point until the referee's final whistle.
On target: 2-4
Catania remain at the bottom of the table following a scoreless draw at home to Hellas Verona in Saturday's lone Serie A match.
The hosts took 16 shots, compared to Verona's eight, but were guilty of poor finishing. Verona managed only one shot on target.
With the draw, Catania moved onto 10 points from 16 matches. Bologna, in 19th place, are two points ahead.
Verona, who drew for the second time this season, remained sixth with 26 points.
AC Milan and AS Roma played to an entertaining draw on Monday night, with the hosts twice coming from a goal down to equalize against the undefeated Giallorossi.
Mattia Destro got things started for the guests with a fine goal after only 13 minutes when, having received Kevin Strootman’s sublime cut-back across the face of goal, he tapped the ball into the back of the net at the far post.
Just before the half-hour mark, however, Milan were level.
Cristian Zapata, who also did yeoman’s service on the defensive side of the ball at the San Siro, temporarily brought the Rossoneri back to level terms when he directed the ball past Morgan De Sanctis following Sulley Muntari’s headed pass from Kaka’s corner.
But Roma were back in front just six minutes after the restart—Strootman calmly converting from the spot after substitute goalkeeper Gabriel was penalized for chopping down Gervinho inside the Milan area.
The hosts then proceeded to pile on the pressure and got their equalizer when Kaka and Mario Balotelli combined to set up Muntari for a shot that beat De Sanctis to the near post.
On target: 4-4
