Watch as Napoli completed a comeback to beat Juventus in a game with three howlers leading to the goals from Alvaro Morata, Matteo Politano and Kalidou Koulibaly.
The Bianconeri had the perfect start against the run of play when Morata caught Kostas Manolas in possession and scored from a tricky angle.
Only David Ospina prevented a similar error when a Lorenzo Insigne back-pass set up Dejan Kulusevski.
However, Juve also made horrible mistakes, as Wojciech Szczesny only pushed Insigne’s curler into the path of Politano.
The goalkeeper did all he could on Moise Kean’s attempted own goal, but Koulibaly pounced on the rebound from a yard to win it.
