Early efforts from Spinazzola and Rrahmani delivered a win for the visitors at the Stadio Olimpico in a match marred by three dismissals.
Three points pushes Conte's side to just one point behind of Italian league leaders AC Milan, who prevailed on Friday. Inter occupy third place but have a chance to go back to the summit with a victory in their later match.
Control Amid Injury Woes
Despite missing several key personnel, the southern Italian side commanded the proceedings with patient build-up play. The first goal came when Matteo Politano's delivery was drilled home by Spinazzola at the back post.
The lead was doubled in the 32nd minute as the defender guided a glancing header from a Politano free-kick into the net. They went close to a third shortly after when Elmas watched his header rattle against the woodwork.
Flashpoints and Red Cards
After the break saw further injury concern for the away side when a winger limped off. The stoppage triggered a brief altercation, leading to bookings for Rrahmani and the home side's Tijjani Noslin—who then was shown a second caution for a foul.
"I must congratulate my players, playing with such a high standard of technical ability and physical strength while preventing the opposition play is not easy," remarked the triumphant manager. "Our performance was at a very high level of play."
Tempers flared again near the end as two opponents were embroiled in a fierce exchange, requiring the coach to step in. Both individuals were shown red cards for their part in the clash.
