MILAN — Napoli didn't let flares and delays affect its performance as Antonio Conte's side ground out a 1-0 win at Lecce to take firm control of Serie A on Saturday.
Giacomo Raspadori scored the only goal to keep Napoli three points ahead of second-placed Inter Milan, which beat Hellas Verona 1-0.
Napoli needs only seven points from the remaining three rounds to win its second league title in three years.
''It's an important step, I can't lie,'' Conte said. ''We're on track and we want to stay there until the end.
''Nobody will remember if we finish second or if we had a good season. History must be written and you do it by winning: The others read it.''
There was a tense atmosphere in Lecce and plenty of banners and chants insulting the league's governing body as fans were furious Lecce was forced to play against Atalanta just three days after the death of club physical therapist Graziano Fiorita.
There was a moving minute's silence before the match but the tension boiled over after kickoff when fans threw flares and fireworks onto the field, causing the match to be temporarily halted in the sixth minute.
Play was going to continue after about four minutes but there was another delay to repair the bottom of the net, where a firework burned a hole.
