Lorenzo Insigne's 86th minute equaliser earned Napoli a hard-fought point against mid-table side Sassuolo in what was a toothless display at the Mapei Stadium.
The visitors, who made eight changes after their 3-0 win against Red Bull Salzburg in the Europa League on Thursday, faced a difficult first half with the Neroverdi creating plenty of opportunities. Former Chelsea winger Jeremie Boga caused the Napoli back line problems in the opening minutes, with his curling effort going just wide after a brilliant run.
Carlo Ancelotti's side looked dangerous on the counter, with Dries Mertens and Adam Ounas being denied only by some sensational last-ditch defending from Sassuolo.
