Victor Osimhen netted with a late header to give Napoli a 1-0 home win over Torino on Sunday and keep them top of Serie A with a perfect record of eight victories from as many games.
The Naples side have 24 points, two more than AC Milan, who came from 2-0 down to triumph 3-2 against Hellas Verona at San Siro on Saturday.
Champions Inter are five points further back in third place after losing 3-1 in Rome to coach Simone Inzaghi's former club Lazio, who moved up to fifth.
Juventus continued their recovery from a poor start, beating AS Roma 1-0 at home thanks to a goal by Moise Kean.
They are now seventh with 14 points.
Roma, who are fourth with 15 points, deserved at least a draw.
At the end of the first half Juve keeper Wojciech Szczesny saved a penalty by Roma's Jordan Veretout.
The Roma players were bemused as to why the referee blew up in the move that led to the spot kick instead of allowing play for go on, with Tammy Abraham touching home an instant after the whistle went.
