Antonio Conte's Napoli maintained their Serie A leadership with a 2-0 win at AC Milan on Tuesday.

Romelu Lukaku and Khvicha Kvaratskhelia scored first-half goals at the San Siro and Napoli opened up a seven-point lead over defending champions Inter Milan, which will visit Empoli on Wednesday.

Lukaku muscled a defender to the ground before scoring from the center of the area early on. Then Kvaratskhelia dribbled past two defenders before launching an angled shot into the far corner before the break.

Milan's center forward Alvaro Morata had a potential goal waved off for offside early in the second half. They are eighth, 11 points back.

Napoli will return to the San Siro in less than two weeks to face Inter. The Partenopei have rebounded strongly after a 10th-place finish last season and are in position to earn their second title in three years.

Conte was hired in June after Napoli went through three different coaches last season. Napoli haven't lost since falling 3-0 at Hellas Verona in their season debut on August 18.

Bologna won 2-0 at Cagliari with goals from Riccardo Orsolini and Jens Odgaard; Lecce beat nine-man Hellas Verona 1-0 with a goal from Patrick Dorgu.
