The Partenopei are still without several players: Alessandro Buongiorno, Franck-Zambo Anguissa, Alisson Santos, Antonio Vergara, Mathias Olivera and Costantino Favasuli are injured, but Scott McTominay is back after undergoing a heart procedure and can play for 20 or 30 minutes today.

Italian sources, including Corriere dello Sport, claim that Allegri will switch to a three-man defence, using Giovanni Di Lorenzo as a right midfielder and leaving Matteo Politano on the bench.

David Neres and Noa Lang are expected to be the attacking wingers, with Kevin De Bruyne deployed as a central midfielder.

Frosinone have earned ten points so far, three more than Napoli, and beat Como 2-0 in their most recent league game before the break. Antonio Raimondo sustained a minor injury before the break, so he’s not expected to start but is available on the bench.
