Lazio’s Luis Alberto and Daichi Kamada secured a 2-1 win for last season’s runners-up at champions Napoli in Serie A on Saturday.
The victory for Maurizio Sarri’s side earned them their first points of the season, while the hosts suffered their first defeat.
Lazio shocked the home crowd by scoring against the run of play on the half-hour when Luis Alberto scored with a cheeky backheel after good work by Felipe Anderson down the right.
Napoli quickly recovered from the setback and levelled two minutes later through Poland midfielder Piotr Zielinski whose deflected low shot went in past Lazio keeper Ivan Provedel.
