Earlier, Atalanta made it three wins out of three with a 5-2 victory over Cagliari.
Juventus was supposed to be playing Napoli later but Gennaro Gattuso’s team has not left Naples after two of its players tested positive for the coronavirus.
League authorities and Juventus have indicated the game should go ahead, raising the prospect of Napoli being handed a 3-0 loss by the league judge for failing to show.
In Rome, Lazio was still smarting from a 4-1 defeat at home to Atalanta and was beset by injury problems.

Atalanta offered up another attacking masterclass, taking its tally to 13 goals in three games.
It was the league’s top scoring team last season with 98 goals.
