Napoli were beaten by Lazio at the Stadio Maradona again – and just like six months ago did so despite dominating the first half.
The Azzurri squandered too many chances and the visitors took the lead the first time they ventured out of their half, Luis Alberto with a sublime backheel.
Piotr Zielinski restored parity almost instantly but Rudi Garcia's side wasted further opportunities to obtain the upper hand.
Soon after the restart Daichi Kamada netted Lazio's second on the counter. Napoli resolutely sought another leveller but it wasn't to be their night.
The team will go again after the international break with a busy fixture list of Champions League and Serie A matches to contend with.
