Paulo Dybala has returned to rescue Juventus in their 1-1 draw at Inter Milan in the Derby d’Italia while both coaches were sent off as Roma ended Napoli’s 100 per cent record in Serie A with a goalless stalemate.
Dybala converted a penalty a minute from time to cancel out Edin Dzeko’s first-half opener for the champions.
Inter remained third, seven points behind Napoli and AC Milan, while Juventus are eighth.
Inter took the lead in the 17th minute against Juve when Hakan Calhanoglu unleashed a screamer from distance that bounced off the right post and Dzeko fired home the rebound.
However, just as it looked as if the Nerazzurri would secure a potentially crucial victory, Juventus were awarded a penalty when Denzel Dumfries fouled Alex Sandro just inside the area.
The decision so incensed Inter coach Simone Inzaghi that he threw a piece of clothing onto the field and was sent off.
Dybala slotted home the spot kick after he had come on in the 65th minute for his first appearance since an injury in the match against Sampdoria last month.
Napoli had won all eight of their league matches in a stunning start to the season but couldn’t find a way past Roma, despite hitting the woodwork twice in quick succession and having a late winner ruled out.
Roma coach Jose Mourinho was sent to the stands for dissent nine minutes from time before his his Napoli counterpart, Luciano Spalletti, was red carded after the final whistle as the referee judged his applause to be ironic, despite the coach’s fervent protests it was genuine.
Napoli should have broken the deadlock on the hour mark but Victor Osimhen hit the right post from point-blank range under pressure, and a desperate tackle by Rick Karsdorp prevented Mario Rui from turning in the rebound.
Roma squandered three opportunities in quick succession as Lorenzo Pellegrini twice missed the target and then Gianluca Mancini headed his free kick narrowly over.
Osimhen thought he had won it two minutes from time but his header was ruled out for offside.
Elsewhere, Giovanni Simeone scored all four goals against his father’s former team as Verona routed Lazio 4-1.
Simeone scored two goals in each half, helped by two assists from Gianluca Caprari, who was also in inspired form.
The 26-year-old Simeone is the son of Atletico Madrid coach Diego Simeone, who played more than 100 matches for Lazio and helped them to the league and cup double in 2000.
Ciro Immobile had halved the deficit for Lazio at the start of the second half.
The match was also notable as the great-grandson of former Italian dictator Benito Mussolini – 18-year-old defender Romano Floriani Mussolini – was on the bench for Lazio for the first time.
Atalanta are fifth after their 1-1 draw with Udinese while Fiorentina went sixth courtesy of a comfortable 3-0 win over relegation-threatened Cagliari.
