Naples: Inter Milan forward Romelu Lukaku scored twice, the first from a run which started inside his own half, to lead his side to an entertaining 3-1 win at Napoli which kept them top of Serie A on Monday.
Lautaro Martinez was also on target as Inter claimed their first away win against Napoli since 1997.
Inter lead the standings on goal difference from Juventus, who beat Cagliari 4-0 earlier on Monday, with both teams on 45 points. The head-to-head record will be used once the two sides have met twice.
Napoli, on the other hand, suffered their second defeat in three games since Gennaro Gattuso replaced Carlo Ancelotti as coach and stayed eighth with 24 points despite showing flashes of their old style.
“This win is worth a lot,” said Inter coach Antonio Conte. “It’s never easy to win at Napoli for anyone. We faced the match with great personality and this will give us more self-confidence and belief. We need to carry on like this.”
