Naples, Italy – Napoli doomed Inter Milan to its fourth 0, at the Stadio San Paolo behind Ezequiel Lavezzi's second-half strike.
Inter manager Claudio Ranieri's seat on the bench certainly got hotter with the loss as his team has failed to pick up a league win in their last six outings.

Inter was left to rue its missed chances as Napoli dictated play for much of the second half.
The breakthrough for the home side came in 59th minute through Lavezzi as he inspired the Blues to fifth place in the Serie A table.
The visitors were given a glimmer of hope to conjure a comeback after Salvatore Aronica was issued a straight red card in the 79th minute, but Ranieri's men could not find a late equalizer.
Napoli jumps ahead of Roma into fifth place, improving to 40 points with its third win in a row. The Blues are unbeaten in their last nine Serie A contests.
Inter's woes continue as the club sits seventh on 36 points.
