SAN SIRO: A Romelu Lukaku penalty was enough to give Inter Milan a 1-0 win against 10-man Napoli at San Siro on Wednesday and move the hosts within a point of Serie A leaders AC Milan. Just one point and one place separated the two sides before kick off, and the game was decided when David Ospina conceded a spot kick midway through the second half, which Lukaku converted. The two captains made an impact in contrasting fashions, as Napoli skipper Lorenzo Insigne was sent off for dissent following the penalty award and Inter goalkeeper Samir Handanovic made some decisive interventions to keep his side in front. Yet Napoli pushed hard for an equaliser with 10 men and Andrea Petagna was denied a late leveller when his shot rattled the post in stoppage time. The victory leaves Inter in second place, one point behind leaders Milan, while Napoli are fourth with 23 points. Pressure was mounting on Inter coach Antonio Conte after his side’s disappointing early exit from the Champions League, where they finished bottom of their group, but he has now overseen a run of five wins in a row in Serie A.
