Cristiano Ronaldo scored twice but champions Juventus had to settle for a point as a late Gervinho double snatched a 3-3 draw after promoted Parma staged an impressive comeback in Serie A on Saturday.
Massimiliano Allegri’s side had already had their confidence shaken after a 3-0 defeat to Atalanta shattered their hopes of winning a fifth straight Coppa Italia.
Saturday’s draw was not the response Allegri had called for ahead of their Champions League last 16 first leg tie against Atletico Madrid on February 20.
“I’m happy for the goals but not the result,” said Ronaldo.
“Parma didn’t do anything special, they waited for us to make a mistake.
“But we’re not worried, we know it will be a great season for Juventus.”
Juve, hit by injuries to defenders Leonardo Bonucci, Giorgio Chiellini and Andrea Barzagli, have now conceded six goals in their last two matches.
“It doesn’t change anything, but we must not take anything for granted,” said Allegri.
“We were too light in defence. It was the first time this back four had played together.”
Sami Khedira rattled the post twice, before Ronaldo opened the scoring after 36 minutes with Daniele Rugani again scoring for the hosts on 62 minutes.
An Antonino Barilla header clawed one back for Parma two minutes later before Ronaldo completed his brace to return to the top of the Serie A goalscorers’ chart with 17.
“At least we satisfied those who complained we weren’t entertaining,” said Allegri.
“But the beautiful football doesn’t pay off, at the end of the day you have got to just kick it away from your goal.”
Earlier Arkadiusz Milik and Lorenzo Insigne scored quick-fire goals and Simone Verdi added a third from the spot as Napoli got back on track.
AC Milan had dented Carlo Ancelotti’s side’s title hopes with a goalless draw in the San Siro last weekend before dumping the southerners out of the Coppa Italia midweek.
“Napoli are back strong,” said Ancelotti.
“Today we found the depth and the ability to quickly overturn the game.
“The two tests against Milan were not our usual selves, we’re back to our normal standard.”
Sampdoria striker Fabio Quagliarella was thwarted in his bid to set a new record of scoring in 12 consecutive Serie A games as the side from Genoa also missed the chance to move up into fourth and the Champions League places.
Napoli skipper Marek Hamsik — reportedly set for a move to China — returned from injury and orchestrated the opener after 25 minutes in the San Paolo Stadium.
The Slovak international’s cross found Jose Callejon who burst through to provide the assist which Milik finished off for his 12th league goal this season.
Less than a minute later Insigne connected sweetly with another Callejon assist for his first league goal in three months.
Napoli were awarded a penalty for a Joachim Andersen handball but despite the calls of “Kalidou, Kalidou” from the crowd for the Senegalese defender to take it after his towering performance, it was Verdi who stepped up to convert in the final minute.
