Juventus and Napoli battled to a 1-1 draw this evening as AC Milan's European hopes suffered a setback when they were held 1-1 at basement side Pescara after a rare mistake by 18-year-old goalkeeper Gianluigi Donnarumma.
Serie A leaders Juventus withstood prolonged pressure as they held out for a tense 1-1 draw at third-placed Napoli in an absorbing match on Sunday.
Sami Khedira gave Juve a seventh-minute lead before Marek Hamsik finished off a flowing exchange of passes to score a superb equaliser on the hour and give Napoli a deserved point.
Juventus, who have 74 points from 30 games, remained 10 points clear of Napoli although their advantage over AS Roma is down to six after the second-placed side's 2-0 home win over Empoli on Saturday.
Earlier, Genoa fans turned their backs to the pitch in protest during a 5-0 home defeat by Atalanta and Diego Falcinelli injured himself celebrating after his late goal at Chievo gave Crotone their first-ever Serie A away win.
Milan gifted the Dolphins an early goal when Donnarumma missed the ball completely as he tried to control Gabriel Paletta's back pass and it flew straight into the goal.
Mario Pasalic levelled before halftime but, despite dominating the second half, Milan failed to find a winner and were left seventh with 54 points.
They dropped four behind of fifth-placed Atalanta who were sent on their way when defender Andrea Conti met Leonardo Spinazzola's cross with a superb overhead kick after 25 minutes.
Alejandro Gomez helped himself to a hat-trick, including one penalty, and Mattia Caldara also scored while the Genoa had Mauricio Pinilla sent off just after the hour. Genoa's hardcore Ultra fans turned their backs to the pitch after the third goal.
Falcinelli curled in an exquisite effort in the 82nd minute to give Crotone a famous 2-1 win which left them five points behind 17th placed Empoli and safety.
Falcinelli was so excited that he tried to jump over an adverising hoarding to celebrate but slipped and had to be stretchered off, though he said later he had merely suffered a cut to his knee.
Andrea Belotti hit the post twice before finally scoring in the 83rd minute to take his season's tally to 22 goals and give Torino a 2-2 draw at home to Udinese.
Palermo's troubles continued when they were beaten 3-1 at home by Cagliari leaving them seven points adrift of safety in the drop zone.
