Napoli were without in-form striker Victor Osimhen as they recorded a 2-1 win over Leece on Friday.
The result saw the Serie A leaders bounce back from their 4-0 defeat to AC Milan.
They have now opened a 19 points gap over second placed Lazio in the league table.
Osimhen was not in action for Luciano Spalletti’s side due to the injury he sustained during the international break.
Napoli broke the deadlock in the 18th minute with their first real chance through skipper Giovanni Di Lorenzo.
A free kick was not cleared effectively, Kim Min-jae put in a cross from the right and Di Lorenzo was ready for a free header.
In the 52nd minute the Lecce were back on level terms thanks to Federico Di Francesco.
Remi Oudin’s free kick was floated to the back post for an Assan Ceesay header off the crossbar, it was not cleared effectively and Di Francesco pounced on the rebound.
However, Lecce shot themselves in the foot by gifting Napoli the second goal in the 64th minute off an own goal by goalkeeper Wladimiro Falcone.
Antonino Gallo tried to cushion a cross back to his own goalkeeper with his chest from six yards, but Falcone was not expecting it and fumbled the ball which ended in the back of the net.
