The two sides face each other tonight for the first of two rounds that will decide one of tournament's finalists.
Lazio Coach Stefano Pioli managed to reduce the gap with Napoli to two points after the Partenopei slipped against Torino, but in their own 3-0 victory over Sassuolo they lost Marchetti.

Lazio Coach Stefano Pioli managed to reduce the gap with Napoli to two points after the Partenopei slipped against Torino, but in their own 3-0 victory over Sassuolo they lost Marchetti.
The Biancoceleste goalkeeper took a knock to his foot and will be rested tonight in favour of Etrit Berisha, though he has still been called up for the bench.
Stefano Mauri is also out with injury, but the rest of the starters are available for Pioli, who can be expected to deploy his favourite trident with Felipe Anderson, Miroslav Klose and Antonio Candreva.
Napoli Coach Rafa Benitez is in a similar predicament as Maggio and Gargano both need to be rested. Il Corriere dello Sport and Eurosport both agree that Faouzi Ghoulam will plug the hole on the left wing, but the two publications propose respectively Giandomenico Mesto and Henrique on the right.
Pending Lorenzo Insigne's imminent return, Napoli will trust in their own trident, with Dries Mertens and Manolo Gabbiadini behind Gonzalo Higuain.
Lazio Probable XI: Berisha; Basta, De Vrij, Mauricio, Radu; Parolo, Biglia, Cataldi; Candreva, Klose, Felipe Anderson.
Napoli Probable XI: Rafael; Mesto, Henrique, Britos, Ghoulam; Inler, Lopez; Gabbiadini, Hamsik, Mertens; Higuain.
