AC Milan Napoli live: Serie A Football Eurosport
Romelu Lukaku and Khvicha Kvaratskhelia were both on target as Napoli beat AC Milan 2-0 at San Siro to extend their lead at the top of Serie A to seven points.
Milan dominated much of the game, but under Antonio Conte, Napoli are tight at the back and potent on the break.
The hosts contributed to their own downfall as Strahinja Pavlovic played on Lukaku and then was brushed over by the Belgian before the opener after five minutes.
The Rossoneri had the best of the match with the ball living in Napoli's half for long periods, but Kvaratskhelia scored a trademark goal, cutting in from the left to score with his right foot.
Milan were unlucky not to be level when Alvaro Morata headed home Samuel Chukwueze's cross just after the break, but from that point onwards they seldom looked like getting back into the game. Paulo Fonseca will be facing questions with his side down in eighth place.
