Juventus remain without a victory this season after they lost to Napoli

Juventus are still without a win this season after falling to Napoli in their first match since Cristiano Ronaldo left for Manchester United. Ronaldo, who helped Juventus win Serie A twice in three seasons, returned United on transfer deadline day in a £12.8 million move and scored twice in Saturday's 4-1 triumph over Newcastle.

In Ronaldo's absence, ex-Chelsea striker Alvaro Morata handed Juve an early lead, but Matteo Politano and Kalidou Koulibaly’s goals helped Napoli come back to win. Koulibaly's winner came with five minutes remaining following a blunder by Moise Kean, who was making his Juventus debut after a two-year loan move from Everton. Kean had only been on the field for three minutes when he nearly scored an own goal with a wayward header from a corner, which Koulibaly converted after goalkeeper Wojciech Szczesny could only parry.
