Dries Mertens netted on two occasions in the second half as they Napoli got the better of a valiant Sampdoria side.
It was the first defeat Sampdoria had suffered since Sinisa Mihajlovic took charge of the Blucerchiati bench six matches ago.
Nenad Krsticic thought he had put Samp 1-0 up only for it to be ruled out for a correct offside call. He later squandered another chance to hand the away side the lead but the first half seemed destined to end goalless.
It was the Doriani who opened the opening stages of the second half with the better of the chances, but Napoli were the ones to break the deadlock.
Mertens volleyed first time a low effort to Da Costa’s left as it fell into the back of the net after just 54 minutes of play, before his second strike followed suit soon afterwards.
The Belgian international got the better of Da Costa for the second time with his free-kick from 25-yards which bounced underneath the diving ‘keepers’ torso.
Catania remained at the foot of the Serie A table despite defeating relegation candidate Bologna 2-0 at the Angelo Massimino.
Francesco Lodi couldn’t have asked for a more perfect return to his hunting ground when he got on the scoresheet for the Elefanti six months after leaving them for Genoa.
It took the midfielder just 23 minutes for the player to have an impact when his free-kick was turned into the back of the net by Gonzalo Bergessio’s header into the far top corner.
Lodi later got on the scoresheet on the hour mark when he confidently converted a penalty to wrap up an impressive 2-0 win.
The victory however does not see them move up the log but they do go equal on points with Livorno who sit second last on the league table.
Alberto Gilardino scored and missed a penalty as he helped Genoa move into the top half of the table with their 2-0 win over Sassuolo at the Luigi Ferraris Stadium.
The hosts broke the deadlock just before the half hour mark thanks to a penalty which resulted from Alessandro Gazzola clattering into Luca Antonelli inside the box. Gilardino smashed the spot kick under the bar
The Grifoni’s lead was doubled just before the break after Moussa Konate crossed from the right. Andrea Bertolacci cushioned volley into the back of the net to take control of the game.
It could have been 3-0 for the home side when they were awarded a penalty just moments after Gianluca Pegolo cleared the ball off the line. Gilardino stepped up again, but this time Pegolo managed to beat it away with his trailing foot to wrap up an impressive win.
Parma bounced back from a goal down to defeat Torino 3-1 at the Ennio Tardini in which Amauri broke his goalscoring drought.
Toro had the more aggressive start and Alessandro Lucarelli risked an own goal when intercepting a Ciro Immobile effort.
Immobile put Torino in front after 21 minutes when he connected to Matteo Darmian’s cross and fired it in at the near post.
It should have been 2-0 by the half hour mark but instead it was Parma who took charge of the game. Marco Marcchioni pulled one back for the hosts when he volleyed in Marco Cassani’s cross.
Amauri almost turned the game around completely 120 seconds later with a cracking shot which struck the upright, but it was Alessandro Lucarelli who put the hosts in the lead in spectacular fashion. The veteran turned in a corner kick with backheel flick at the edge of the six-yard box.
Amauri ended his Parma goal drought with a solo effort which saw him hold off Kamil Glik to put the ball into the back of the net from eight yards out to make sure the result was beyond reach.
Udinese-Hellas Verona (1-3)
Hellas Verona were the only team to win on the road on Monday afternoon after they recorded a 3-1 win over Udinese at the Stadio Bentegodi.
Luca Toni stole the show for the Butei with his brace in Friuli as the visitors took the lead thanks to an absolute howler from goalkeeper Zeljko Brkic.
The shot-stopper allowed a seemingly harmless Toni snapshot slip between his hands and legs as he failed to prevent the ball from spilling into the back of the net.
Udinese tried to find their way back as they pressed for an equalizer with their waves of attacks but couldn’t fashion any sort of strike to draw things level.
Verona instead doubled their lead six minutes from the break when Toni sprung the offside trap from Romulo’s pass to flick it over Brkic.
Roberto Pereyra got Udinese back into it before the half-time break with a sensational goal. He took the ball away from his marksmen and volleyed it into the top corner.
But the victory was wrapped up by Juan Iturbe. He came off the bench to work his way between defenders and hit home a strike while in the process of falling to the floor.
Miroslav Klose struck ten minutes from time to hand Lazio their first win under Edy Reja with a 1-0 victory over Inter at the Stadio Olimpico on Monday evening.
The fixture was the last encounter of a full day of matches and it was a rather tame affair which saw Inter squander plenty of their possession while Lazio capatilised on their opportunities.
The first-half ended goalless and it spilled over well into the second half before Klose pounced in the 80th minute. The German struck home a well-worked volley from Antonio Candreva’s shot to secure a crucial victory.
The victory means Lazio will into tenth place on the log while Inter relinquish fifth place to Hellas Verona, who beat Udinese 3-1 earlier in the afternoon.
