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.

Wesley Sneijder came within inches of giving Inter the lead just before the break as he curled a free kick toward goal that looked destined for the upper corner, but sailed just wide of the post, ensuring a scoreless first half.

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.

Atalanta 4, Roma 1

Bergamo, Italy - German Denis notched a hat trick to help guide Atalanta to a shock 4-1 win over nine-man Roma at the Stadio Atleti Azzurri d'Italia on Sunday.

Roma had little hope for a comeback as its leading scorer, Daniel Osvaldo, was sent off 36 minutes from time. Things went from bad to worse for the visitors as substitute Marco Cassetti was dismissed for dissent with eight minutes remaining.
