MILAN - Juventus, Roma and Napoli hit 11 goals between them to deliver a blow to pursuers Fiorentina and Verona as Milan were stunned 4-3 thanks to four goals from teenage striker Domenico Berardi on Sunday.
Juventus had been looking for a club record of 11 successive wins and despite conceding a 21st minute opener to Mauricio Pinilla the champions fought back in clinical fashion with Fernando Llorente netting twice in a 4-1 win at Cagliari.
Roma began the day eight points behind leaders Juve but had little trouble dispatching Genoa, who were reduced to 10 men before the hour, 4-0.
Alessandro Florenzi led the rout with a sublime overhead kick, with further goals coming courtesy of club captain Francesco Totti, Maicon and Mehdi Benatia.
Totti, hitting his first goal in nine months, hailed Juve's campaign but said the title race was not over.
Napoli were two points further adrift but despite a potentially tricky fixture returned from high-flying Verona with a precious 3-0 win.
Napoli coach Rafael Benitez suggested the scoreline flattered his side.
