Inter tasted victory over Napoli at the San Paolo for the first time in a Serie A match since October 1997 thanks to Romelu Lukaku's double.
Romelu Lukaku scored a double as Inter comfortably beat Napoli 3-1 for their first Serie A win at the San Paolo in just over 22 years.
Inter were on Monday briefly replaced at the top of the league by Juventus, who downed Cagliari 4-0, but regained their spot at the summit with an impressive triumph.
Lukaku struck twice in the first half, the second coming thanks to a blunder from Napoli goalkeeper Alex Meret, before Arkadiusz Milik halved the deficit in the 39th minute.
