First-half strikes from Leonardo Spinazzola and Amir Rrahmani delivered a win for Napoli at the Stadio Olimpico in a match marred by multiple sendings-off.
The win pushes Napoli to within a single point of Italian league pace-setters Milan, who prevailed on Friday. Inter Milan hold third place but can return to the summit with a victory in their evening match.
Hampered by the absence of several key personnel, the southern Italian side controlled the game with patient build-up play. The first goal arrived when Matteo Politano's cross was drilled home by Spinazzola at the far post.
The lead was doubled in the 32nd minute as Rrahmani guided a header from a Politano free-kick into the net. They came close to a third goal shortly after when Eljif Elmas watched his header crash against the woodwork.
After the break saw more worry for the away side when a winger was forced off. This incident triggered a brief altercation, resulting in bookings for Rrahmani and the home side's Tijjani Noslin—who subsequently was shown a second yellow for a challenge.
"I must congratulate the lads, performing with such a high standard of technical ability and intensity while preventing the opposition play is difficult," remarked the triumphant manager. "We played at a exceptional level of quality."
Tempers flared again near the end as players from both sides were embroiled in a heated confrontation, requiring the manager to step in. The two players were dismissed for their involvement in the incident.
Over in La Liga, the Andalusian side suffered a 3-0 defeat at home to struggling Levante. Levante took control with a well-worked team goal before scoring two further goals in the second period to seal a convincing victory.
Meanwhile, Los Blancos host significant must-win when they welcome Betis, after their rivals increased their lead at the top. Later on late game, Atlético Madrid travel to face Real Sociedad.
