A hat-trick from Edinson Cavani has helped Napoli to a 4-1 win over Roma at the Stadio San Paolo.

The victory has seen Walter Mazzarri's side move up to third place in the Serie A table.

Cavani gave the hosts the lead with just four minutes on the clock with a poked finish past Roma goalkeeper Mauro Goicoechea.

The striker made it 2-0 early in the second half when he turned in the area before firing in.

Cavani then completed his hat-trick in the 70th minute thanks to a header from Goran Pandev's corner.

Pablo Osvaldo pulled a goal back for the visitors soon after, but they ended the match with 10 men as Miralem Pjanic picked up a second booking with 15 minutes left to play.

The three points were secured in the final moments for the home side through Christian Maggio's strike.
